The most ancient name known is recorded by Theophrastus in about 300-325 BCE, κρύσταλλος or kristallos. The varietal names, rock crystal and Bergkristall (German), preserve the ancient usage. The root words κρύοσ signifying ice-cold and στέλλειυ to contract (or solidify) suggest the ancient belief that kristallos was permanently solidified ice.\r\n\r\nThe earliest printed use of \"querz\" was anonymously published in 1505, but attributed to a physician in Freiberg, Germany, Ulrich Rülein von Kalbe (a.k.a. Rülein von Calw, 1527). Agricola used the spelling \"quarzum\" (Agricola, 1530) as well as \"querze\", but Agricola also referred to \"crystallum\", \"silicum\", \"silex\", and silice\". Tomkeieff (1941) suggested an etymology for quartz: \"The Saxon miners called large veins - Gänge, and the small cross veins or stringers - Querklüfte. The name ore (Erz, Ertz) was applied to the metallic minerals, the gangue or to the vein material as a whole. In the Erzgebirge, silver ore is frequently found in small cross veins composed of silica. It may be that this ore was called by the Saxon miners 'Querkluftertz' or the cross-vein-ore. Such a clumsy word as 'Querkluftertz' could easily be condensed to 'Querertz' and then to 'Quertz', and eventually become 'Quarz' in German, 'quarzum' in Latin and 'quartz' in English.\" Tomkeieff (1941, q.v.) noted that \"quarz\", in its various spellings, was not used by other noted contemporary authors. \"Quarz\" was used in later literature referring to the Saxony mining district, but seldom elsewhere.\r\n\r\nGradually, there were more references to quartz: E. Brown in 1685 and Johan Gottschalk Wallerius in 1747. In 1669, Nicolaus Steno (Niels Steensen) obliquely formulated the concept of the constancy of interfacial angles in the caption of an illustration of quartz crystals. He referred to them as \"cristallus\" and \"crystallus montium\".\r\n\r\nTomkeieff (1941) also noted that Erasmus Bartholinus (1669) used the various spellings for \"crystal\" to signify other species than quartz and that crystal could refer to other \"angulata corpora\" (bodies with angles): \"In any case in the second half of the XVIIIth century quartz became established as a name of a particular mineral and the name crystal became a generic term synonymous with the old term 'corpus angulatum'.\"","2026-03-28

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 5700 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003Cp>The silicates are the most abundant and chemically complex group of minerals.  All silicates have silica as the basis for their chemistry.  \"Silica\" refers to SiO2 chemistry.  The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4.  Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens \"belong\" to each silicon.  The resulting formula for silica is thus SiO2, not SiO4.\n\u003C\u002Fp>\u003Cp>Dumortierite is a scarce silicate mineral having the formula (Al,Fe)7(SiO4)3(BO3)O3 - aluminum iron borosilicate.

First, it is dramatically sceptred. Second, it shows both amethyst blushes and smoky tones, similar to Brandberg quartzes in appearance. Third, the top part of the sceptre shows interesting skeletal growth on one side. Fourth, there are inclusions of bright red little lepidocrocite crystals. And once I realized that this specimen had all of these things, I decided to look to see if there was an enclosed moving bubble (enhydro) that would cap it all off. After a few seconds of looking, I found an easily visible one! So, in one crystal, you have just about everything possible going on for an African quartz: amethyst, smoky, sceptering, lepidocrocite inclusions, an enhydro bubble, and skeletal growth.

The lepidolite is wonderful for this find. As a bonus, on the bottom side, you have a rare mineral species first described from this locality in 2006. Guimaraesite is a newly described complex calcium\u002Fzinc\u002Fmagnesium\u002Firon beryllium phosphate, which comes from an unnamed pegmatite working in this valley. This specimen is a complete floater quartz cluster the size of a large grapefruit, with exception only of one small bit on one side which is contacted.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 4900 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Molybdenite is a molybdenum sulfide mineral (MoS2).  It has hexagonal crystals, metallic luster, a bright silvery color, and a dark gray streak.  It is fairly soft (H=2) and has one cleavage.  Molybdenite is especially distinctive in being flexible - thin scales or plates of molybdenite will easily bend but won't snap back into shape like biotite or muscovite mica.\n\u003C\u002Fp>\u003Cp>Molybdenite is nearly identical to graphite (C) in its physical characteristics (see: \u003Ca rel=\"nofollow\" class=\"external text\" href=\"https:\u002F\u002Fwww.flickr.com\u002Fphotos\u002Fjsjgeology\u002Fsets\u002F72157650963514503\">www.flickr.com\u002Fphotos\u002Fjsjgeology\u002Fsets\u002F72157650963514503\u003C\u002Fa>).

The famed Musonoi is the Type Locality for Oosterboschite. This piece is from the Howard Belsky Collection, who collected many rare species. We believe the splendent gray crystals on one end surrounded by a green mineral are the oosterboschite. The quartz matrix holds several vugs richly lined with gemmy, green cuprosklowdoskite needles. The brown crystals richly lining one vug could be oxidized trogtalite, as MINDAT lists this species as being rose-violet. X-ray work would be needed to confirm species identifications in a normal case but, as this is from the Belsky Collection, it’s pretty certain to be legitimate. He had his own analytical setup and did much work with friends in museums, specializing in rarities.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",{"id":3811,"source_url":3812,"license_code":1718,"credit_html":3813,"title":3814,"description":3809,"author":1747,"original_width":1900,"original_height":1756},18140,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=27714291","Robert M.

It must have ended up with Roebling's friend Gage shortly thereafter either by further gifting or by sale from the collection. This specimen would come with a color copy of the original label. Originally the mineral was described under the name \"lotrite\" from the southern Carpathian Mountains (Murgoci, 1901). Charles H. Palache, who in 1920 made the first systematic study of the secondary minerals in the altered copper lodes for the Calumet and Hecla Copper Mining Company, noted a green mineral which he believed to be a new mineral closely related to the zoisite-epidote family.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 5100 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The silicates are the most abundant and chemically complex group of minerals.  All silicates have silica as the basis for their chemistry.  \"Silica\" refers to SiO2 chemistry.  The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4.  Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens \"belong\" to each silicon.  The resulting formula for silica is thus SiO2, not SiO4.\n\u003C\u002Fp>\u003Cp>The simplest & most abundant silicate mineral in the Earth's crust is quartz (SiO2).  All other silicates have silica + impurities.  Many silicates have a significant percentage of aluminum (the aluminosilicates).\n\u003C\u002Fp>\u003Cp>Quartz (silicon dioxide\u002Fsilica - SiO2) is the most common mineral in the Earth's crust.  It is composed of the two most abundant elements in the crust - oxygen and silicon.  It has a glassy, nonmetallic luster, is commonly clearish to whitish to grayish in color, has a white streak, is quite hard (H≡7), forms hexagonal crystals, has no cleavage, and has conchoidal fracture.  Quartz can be any color: clear, white, gray, black, brown, pink, red, purple, blue, green, orange, etc.\n\u003C\u002Fp>\u003Cp>The unremarkable quartz crystal shown above is actually a pseudomorph.  This is quartz after beta quartz (also known as quartz-beta).  Beta quartz is a high-temperature polymorph of quartz - it has the same formula, SiO2.  Beta quartz is unstable at Earth-surface temperatures, so during cooling, the molecular structure became slightly rearranged, resulting in ordinary quartz.  However, the quartz retains the crystal shape of the original beta quartz.  Beta quartz has hexagonal crystals, while quartz technically forms trigonal crystals that have a hexagonal outline (see details of quartz crystals at: <a href=\"\u003Ca rel=\"nofollow\" class=\"external free\" href=\"https:\u002F\u002Fwww.mindat.org\u002Fmin-3337.html\">https:\u002F\u002Fwww.mindat.org\u002Fmin-3337.html\u003C\u002Fa>\" rel=\"nofollow\">www.mindat.org\u002Fmin-3337.html<\u002Fa>).\n\u003C\u002Fp>\u003Cp>This example of beta quartz comes from a polymetallic sulfide ore body at the famous Dalnegorsk skarn deposit in far-eastern Russia.\n\u003C\u002Fp>\u003Cp>Locality: Verkhneye Mine, Dalnegorsk, Primorsky Krai, far-eastern Russia\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>See info. on beta quartz at:\n<a href=\"\u003Ca rel=\"nofollow\" class=\"external free\" href=\"https:\u002F\u002Fwww.mindat.org\u002Fmin-7395.html\">https:\u002F\u002Fwww.mindat.org\u002Fmin-7395.html\u003C\u002Fa>\" rel=\"nofollow\">www.mindat.org\u002Fmin-7395.html<\u002Fa>\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Photo gallery of quartz:\n\u003C\u002Fp>\n<a href=\"\u003Ca rel=\"nofollow\" class=\"external free\" href=\"http:\u002F\u002Fwww.mindat.org\u002Fgallery.php?min=3337\">http:\u002F\u002Fwww.mindat.org\u002Fgallery.php?min=3337\u003C\u002Fa>\" rel=\"nofollow\">www.mindat.org\u002Fgallery.php?min=3337<\u002Fa>",1023,945,{"id":3956,"source_url":3957,"license_code":1718,"credit_html":3958,"title":3959,"description":3960,"author":1747,"original_width":1763,"original_height":3961},20580,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10120507","Robert M.

The tetrahedrite occurs as sharp , metallic crystals and may actually be overtopping large bornite crystals, it seems. The piece is very nearly pristine with but a few faint marks of wear seen by the educated eye only, and NO restoration or repairs whatsoever. The large central crystal is 5 cm across, and it is draped with fluorite and smaller rhodo crystals. The color I would rate as an 8.5 on a scale of 10 - and I can say honestly that it is what we called good color back when they were being mined - as opposed to what often passes for \"acceptable color\" on specimens I see at market today. The lustre is high, and the color saturation is uniform. This is an EXCELLENT piece overall, and has a huge amount of color for the price (again, considering what else I have seen on the market these days). The fluorites are sparkling and a nice lavender hue, in person. I purchased this piece for my private collection, of fine large Sweet Home rhodochrosite specimens, in 2006 at the Munich show. I have held it since, and am selling a few of my private collection rhodochrosites now only to finance acquiring a yet larger specimen.

Most of them average 1 cm. Sprinkled amonst the red, are sharp black clusters of metallic tetrahedrite which make for a really nice contrast. The overall shape of the piece is very sculptural with a slight curvature to it, not \"cookiecutter\" or blocky as so many large specimens are trimmed out from the plates they are sawed out on. The piece has the TOP CHERRY COLOR. This is not off-color, not strawberry in hue as so many you see on the market today are. This is a piece that has the color and lustre combination (important!) that, even \"way back when\" only a few years ago when the mine was still open, even in context of the many finds after 2001 or so before it closed, you couldnt get. Most people then and now settle for pieces with lesser color saturation, less lustre, and more damage...its all that is out there. I sold this one back in the late 90s and was happy to get it back recently! You just cannot find large cabinet rhodos of quality around. And this is one I am happy to have owned again and again, and would do so a third time. They appreciate at such a fast clip every year, 20% or so it seems, that I cannot replace my supply except by buying entire collections with specimens in them. So, I rarely sell mine. Or, as with this one, I'll give it a few months on the web and then pull it down and stash it for the future. Just cashflow...this is one rock I am happy to keep as rhodo today is \"red gold\" in the bank better than the cash is. Comes with custom lucite base for easy display.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 6000 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003Cp>The silicates are the most abundant and chemically complex group of minerals.  All silicates have silica as the basis for their chemistry.  \"Silica\" refers to SiO2 chemistry.  The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4.  Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens \"belong\" to each silicon.  The resulting formula for silica is thus SiO2, not SiO4.\n\u003C\u002Fp>\u003Cp>Tourmaline is a classic \"garbage-can mineral\" - it has a little bit of just about everything.  Tourmaline can be given the formula (Na,Ca)(Li,Mg,Al)(Fe,Mn,Al)6(BO3)3(Si6O18)(OH,F)4 - sodium calcium lithium magnesium iron manganese hydroxy-fluoro-boro-aluminosilicate.  Tourmaline has a nonmetallic luster, varies in color but is often blackish, has a white streak, is quite hard (H = 7 to 7.5), frequently has elongated crystals with subtriangular cross-sections and striated faces, no cleavage, and conchoidal fracture.\n\u003C\u002Fp>\u003Cp>Tourmaline is a group of minerals, the most common of which is the blackish-colored, Fe-rich schorl.  The dark brown, Mg-rich dravite is another moderately common variety of tourmaline.  Other varieties include achroite, elbaite (Li & Na-rich), indicolite, liddicoatite (Li & Ca-rich), rubellite, verdelite, and others.  The latter-listed tourmalines are often richly colored (greenish, yellowish, reddish, pinkish, bluish, multicolored).\n\u003C\u002Fp>\u003Cp>Tourmaline is moderately common in pegmatites and some metamorphic rocks.  It can even be rock-forming - see the scarce rock tourmalinite (www.flickr.com\u002Fphotos\u002Fjsjgeology\u002F15095512541).\n\u003C\u002Fp>\u003Cp>The sample seen here is a moderately large quartz crystal that is blackish-colored from abundant included tourmaline.\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Photo gallery of tourmaline:\n\u003C\u002Fp>\nwww.mindat.org\u002Fgallery.php?min=4003",1604,{"id":4293,"source_url":4294,"license_code":2015,"credit_html":4295,"title":4296,"description":4290,"author":2019,"original_width":4297,"original_height":4298},24434,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433131","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433131\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Tourmalinated quartz 2.jpg",3963,1532,{"id":4300,"source_url":4301,"license_code":2015,"credit_html":4302,"title":4303,"description":4290,"author":2019,"original_width":4304,"original_height":4305},24435,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433139","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433139\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Tourmalinated quartz 3.jpg",3748,2510,{"id":4307,"source_url":4308,"license_code":2015,"credit_html":4309,"title":4310,"description":4290,"author":2019,"original_width":4311,"original_height":2045},24436,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433142","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433142\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Tourmalinated quartz 4.jpg",3876,{"id":4313,"source_url":4314,"license_code":2015,"credit_html":4315,"title":4316,"description":4290,"author":2019,"original_width":2044,"original_height":4317},24437,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433143","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433143\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Tourmalinated quartz 5.jpg",2688,{"id":4319,"source_url":4320,"license_code":2015,"credit_html":4321,"title":4322,"description":4290,"author":2019,"original_width":2044,"original_height":4323},24438,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433147","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433147\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Tourmalinated quartz 6.jpg",2834,{"id":4325,"source_url":4326,"license_code":2015,"credit_html":4327,"title":4328,"description":4290,"author":2019,"original_width":4329,"original_height":3081},24439,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433149","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433149\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Tourmalinated quartz 7.jpg",3398,{"id":4331,"source_url":4332,"license_code":2015,"credit_html":4333,"title":4334,"description":4290,"author":2019,"original_width":2044,"original_height":2045},24440,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433150","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=154433150\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Tourmalinated quartz 8.jpg",{"id":4336,"source_url":4337,"license_code":1783,"credit_html":4338,"title":4339,"description":2606,"author":2607,"original_width":569,"original_height":569},24588,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=1955935","Dave Dyet http:\u002F\u002Fwww.shutterstone.com http:\u002F\u002Fwww.dyet.com, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=1955935\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Augelite w- trolleite and quartz Basic aluminum phosphate Champion Mine White Mountains Mono County California 2298.jpg",{"id":4341,"source_url":4342,"license_code":1718,"credit_html":4343,"title":4344,"description":4345,"author":1747,"original_width":4346,"original_height":1930},24635,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10457860","Robert M.

I got some directly at the time from curator Dmitriy Belakovskiy, who has himself been to this remote location on at least one expedition.

Metallic, semimetallic (metalloid), and nonmetallic elements are known in their native state as minerals.\n\u003C\u002Fp>\u003Cp>Gold (Au) is the most prestigious metal known, but it's not the most valuable.  Gold is the only metal that has a deep, rich, metallic yellow color.  Almost all other metals are silvery-colored.  Gold is very rare in crustal rocks - it averages about 5 ppb (parts per billion).  Where gold has been concentrated, it occurs as wires, dendritic crystals, twisted sheets, octahedral crystals, and variably-shaped nuggets.  It most commonly occurs in hydrothermal quartz veins, disseminated in some contact- & hydrothermal-metamorphic rocks, and in placer deposits.  Placers are concentrations of heavy minerals in stream gravels or in cracks on bedrock-floored streams.  Gold has a high specific gravity (about 19), so it easily accumulates in placer deposits.  Its high density allows prospectors to readily collect placer gold by panning.\n\u003C\u002Fp>\u003Cp>In addition to its high density, gold has a high melting point (over 1000º C).  Gold is also relatively soft - about 2.5 to 3 on the Mohs Hardness Scale.  The use of pure gold or high-purity gold in jewelry is not desirable as it easily gets scratched.  The addition of other metals to gold to increase the hardness also alters the unique color of gold.  Gold jewelry made & sold in America doesn’t have the gorgeous rich color of high-purity gold.\n\u003C\u002Fp>\u003Cp>The sample shown above is hydrothermal vein rock from the Grant Mine, northwest of the city of Fairbanks, Alaska.  The mine produced gold, silver, antimony, lead, and tungsten.  Two hydrothermal veins were the principal targets of mining at this locality - the O’Dea Vein and the Irishman Vein.  This specimen may be from the O’Dea Vein, which varies in width from 6 inches to over 6 feet.  Both veins are developed in fault zones in Fairbanks Schist host rocks of probable Proterozoic age.  The rock is dominated by whitish quartz (this has been described as a “quartz breccia”), which has been mostly stained pale yellowish to reddish-brown by iron oxide.  Native gold occurs throughout the rock, plus a gray to dark gray sulfide mineral.  Minerals reported from the O’Dea Vein include quartz (SiO2 - silicon dioxide), gold (Au), arsenopyrite (FeAsS - iron arsenic sulfide), galena (PbS - lead sulfide), pyrite (FeS2 - iron sulfide), stibnite (Sb2S3 - antimony sulfide), muscovite mica (KAl2(AlSi3O10)(OH)2 - potassium hydroxy-aluminosilicate), goethite (FeO(OH) - iron hydroxy-oxide), and scheelite (CaWO4 - calcium tungstate).  The O’Dea Vein also includes fragments of Fairbanks Schist host rock and fault mylonite.  Isotopic dates on vein-fault minerals from the nearby Ryan Lode Mine, which is probably developed on the same fault zone as the Grant Mine, are 88 to 89 Ma (Late Cretaceous).  Dates from other mines in the district are also Late Cretaceous (for example, 92 Ma at the Tolovana Mine and 103 Ma at the Hi-Yu Mine).\n\u003C\u002Fp>\u003Cp>Locality: Grant Mine (SE1\u002F4 section 28, T1N, R2W, Fairbanks D-2 topographic quadrangle), ~0.75 air-miles south of the Ester Dome Road-St. Patrick Road intersection, eastern side of Ester Dome, southwestern Fairbanks Mining District, Tintina Gold Province, Fairbanks North Star Borough, northwest of the city of Fairbanks, central Alaska, USA\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Grant Mine geology mostly synthesized from:\n\u003C\u002Fp>\u003Cp>Freeman & Schaefer (2001) - Alaska resource data file, Fairbanks quadrangle.

I think most were collected in the 1970s by Don Doell and friends, of this style. This particular specimen is a choice miniature with a 1.4 cm crystal perched smack dab in the center. These pseudohexagonal crystals have unique form, and look more like a biological growth of coral, than a crystal per se. Still on the specimen is much of the original pocket coating, which is comprised of several other rare species (primarily dresserite), on calcite and small quartz crystals. The little black microcrystals atop may be donnayite but I am not sure. Specimens, particularly with good yellow color, are uncommon and always were...and always will be. According to MINDAT: The quarry has been inactive since 1981 and will never be active again. It is in the central part of the city of Montr�al (pop. over 2.5 million), in a residential area, and owned by the City. It is used for snow dumping in winter. Actually, the quarry could be listed by its city address: 3701 rue Jarry Est, Montreal. ( Although not a US classic, it just fit in well with the update and was handy.)\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",{"id":4505,"source_url":4506,"license_code":1718,"credit_html":4507,"title":4508,"description":4509,"author":1747,"original_width":4510,"original_height":1755},28005,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10151796","Robert M.

The quartz hosts an internal phantom generation of quartz, that is richly included by powder blue ajoite. Now, often the inclusions are dispersed in the quartz , but seldom do you see a phantom within, concentrating the color as this one does. The crystal is complete all around, and shows extraordinary clarity looking through to the phantom zone within. I have seen literally hundreds of these, and in this size range, few have stood out to me as starkly as this piece, which I saw at the Munich show with a direct source. Moreover, it is complete and sharp, and shows off the inclusions without need of polishing. It really is one of the sharpest and finest in its size class. After cleaning, we found that it is technically a floater - rough at the bottom, but microcrystallized and complete.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",910,{"id":4722,"source_url":4723,"license_code":1718,"credit_html":4724,"title":4725,"description":4726,"author":1887,"original_width":1802,"original_height":1789},31683,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=15909394","Parent Géry, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=15909394\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Quartz avec ajoïte (République d'Afrique du Sud) 2.JPG","cristaux de quartz avec ajoïte",{"id":4728,"source_url":4729,"license_code":1718,"credit_html":4730,"title":4731,"description":4726,"author":1887,"original_width":4732,"original_height":1789},31684,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=15909579","Parent Géry, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=15909579\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Quartz avec ajoïte (République d'Afrique du Sud) 5.JPG",3968,{"id":4734,"source_url":4735,"license_code":1718,"credit_html":4736,"title":4737,"description":4726,"author":1887,"original_width":1802,"original_height":1789},31685,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=15909650","Parent Géry, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=15909650\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Quartz avec ajoïte (République d'Afrique du Sud) 6.JPG",{"id":4739,"source_url":4740,"license_code":1728,"credit_html":4741,"title":4742,"description":4743,"author":1787,"original_width":2513,"original_height":2514},31686,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=75818253","Géry PARENT, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=75818253\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Quartz with ajoite 2.jpg","Quartz with ajoite : Messina Mine, Messina District,  Limpopo Province, South Africa",{"id":4745,"source_url":4746,"license_code":1728,"credit_html":4747,"title":4748,"description":4749,"author":2457,"original_width":4750,"original_height":4751},31845,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=130003437","Raimond Spekking, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=130003437\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Axinite, Quartz, Apatite, Albite.

The piece is from a famous old deposit, which today produces beryls but nothing so impressive as what you see here. The matrix of claeavelandite is actually typical of this region, and quite nice in its own right. The morganite, though, has KILLER color, really a hot pink and a form more associated with modern material from Afghanistan than anything from Brazil. Most people would immediately peg this as an Afghani piece, I would bet (and in fact this has happened). However, the giveways are the slightly different cleavelandite (more sharp and sparkly than Paprok material) and the coloration and style of the small tourmaline included in the morganite. The morganite itself is complete in about 95% of its display area, with only a small bit in one corner restored with matching epoxy. The morganite is VERY sharp, totally undamaged otherwise, and measures 4.5 INCHES (11.2 cm) across. Believe it or not, this piece came up from Brazil in the 1970s, in a suitcase, as a specimen that was triple this current size and mass at the time. A natural history collector purchased it from the Amsterdam Sauer Museum in Rio de Janiero in around 1976. This museum was both a display for the owner's well known personal collection and a storefront for selling specimens outright. Apparently, this collector simply put it on a coffee table where it sat, unappreciated by anybody in the core mineral community, for the next 30 years.

These pseudohexagonal crystals have unique form, and look more like a biological growth of coral, than a crystal per se. Still on the specimen is much of the original pocket coating, which is comprised of several other rare species (primarily dresserite), on calcite and small quartz crystals.

The Gold has a lustrous, bright, metallic appearance, and stands out beautifully against the snow-white Quartz and black Sphalerite matrix. It was collected by Andy Sutyak of Ouray, Colorado in 1927. The piece later went to Clancy Fleetwood (Brian Kosnar's great-grandfather), and in 1984 became part of the famous Colorado mineral collection of Richard Kosnar, whose hand-painted catalogue number (G1084Tb) is on the bottom of the specimen.

The 7.5 cm tall, black, lustrous, ferberite crystal is aesthetically perched above and amidst colorless, gemmy quartz crystals that reach 6.5 cm in length. The quartz has some interesting iron oxide staining that could probably be removed, but adds a touch of color. The termination of the ferberite is striking for its sharp textbook form and 3-dimensionality - you can display it form any side.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are about 5400 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The silicates are the most abundant and chemically complex group of minerals.  All silicates have silica as the basis for their chemistry.  \"Silica\" refers to SiO2 chemistry.  The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4.  Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens \"belong\" to each silicon.  The resulting formula for silica is thus SiO2, not SiO4.\n\u003C\u002Fp>\u003Cp>The simplest & most abundant silicate mineral in the Earth's crust is quartz (SiO2).

Dr. Werner Paar Collection Hessite is a very rare silver telluride that occurs at its best, in monster crystals as you see here, ONLY from this old classic locality. Specimens are extremely hard to obtain today and the few I have ever gotten tend to sell quickly. In europe, I have seen far inferior specimens to this priced at over double the price, and in euros no less. So I think that here, my friend is parting with a true treasure (even though it was a duplication, I argued for him to keep it...). The area with good xls (one elongated xl is really important and dramatic!) measures approximately 3x2 cm which is a rather large and impressive coverage. There is even some very microscopic gold in attendance. The piece retains its original patina, uncleaned by any acids or chemicals to brighten the hessite (although this is easily done with silver cleaners) or to change the quartz from iron-stained orange to a contrasting white color (also easily done with simple iron-out cleaners). I love the historic look of the piece. It is clean...by no means \"dirty\"...but it retains the look of an ancient specimen and is not \"modernized\" as too many are into a shiny silver crystal group on sparkling white quartz.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",448,{"id":6247,"source_url":6248,"license_code":1718,"credit_html":6249,"title":6250,"description":6251,"author":1747,"original_width":518,"original_height":1930},58807,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10461010","Robert M.

The fact that there are mines on this mountain is incredible considering the elevation and treacherous conditions. Recently, (July of 2009) there was a new find of Hübnerite from this famous mine. This is confirmed Hübnerite, and not Ferberite. There are a few minor spots on the side of the specimen where if one were to shine a very bright light, they will see small red reflections, which is proof to the presence of manganese in the crystals.

This is a VERY choice piece that came out in the 1980s and has long been in a private German collection. The lustre, color, sharpness of the crystals is superb. It is nice that they have REAL terminations instead of the usual fuzzy-terminated style from the locality where the terminations just sort of taper off. Here, we have lustrous, chisel-shaped faces. The largest hubnerite crystal measures over 5.0 cm in length.

This incredible dramatic specimen, about 13 inches across, is just amazing to me in that it survived the aeons. I think the aesthetics speak for itself. The small inclusions you see are casued by microlite, taken into the crystals during growth. The piece has one repair about the midpoint, and I actually purchased it in two portions - and we only then found they went together in somewhat of a minor miracle! The two portions had come apart in geologic time, and were separated in the pocket when it was found, not realized to connect. There is a small discontinuity to the smoothness at the join because, over time, aquamarine recrystallized minutely over the break and so each half has a few millimeters of extra growth added after the break. When they were rejoined, we left this slight dip at the join as illustrative of the natural processes which form such impressive large pegmatite specimens, rather than grind down the secondary growth to make a perfectly smooth fit.

The smokies, and the perfection of the piece overall in its display, make it of a quality for any collector to consider, not just those who like the \"rare uglies\"!\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",394,{"id":6514,"source_url":6515,"license_code":1718,"credit_html":6516,"title":6517,"description":6518,"author":1747,"original_width":1930,"original_height":4184},62247,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10444870","Robert M.

The type locality for this material is Mt. Mica, Maine, and the crystals at that find barely approached 1 mm in diameter. A few years ago, Luiz Menezes made a discovery of what are the finest crystallized Kosnarite specimens in existence with crystals up to 4 mm. This piece doesn't have crystal up to 4 mm, but it does feature sharp, lustrous, cream color, pseudo-cubic (trigonal) crystals on a group of gemmy Quartz crystals. If you look under magnification, you'll see a small truncated face on each \"cube\" of Kosnarite on this specimen, which is actually a pinacoid or a \"c\" face as these crystals are trigonal and not isometric as they might appear.

The rock is part the Butte Quartz Monzonite (a.k.a. Butte Pluton), which is a component of the Boulder Batholith.  The Butte Quartz Monzonite (\"BQM\") formed 76.3 million years ago, during the mid-Campanian Stage in the Late Cretaceous.  BQM rocks have been intruded and altered by hydrothermal veins (= the band through the middle of the picture) that often bear valuable metallic minerals - principally sulfides.  Vein mineralization has been dated to 62-66 million years ago, during the latest Maastrichtian Stage (latest Cretaceous) and Danian Stage (Early Paleocene).

While not a huge producer according to Butte standards, by 1944 hardrock miners had removed a respectable 7,626,540 ounces of silver as well as lead and zinc from her depths.  Cool temperatures between 55 and 65 degrees made the Orphan Girl - affectionately nicknamed \"Orphan Annie\" or \"the Girl\" - a desirable place to work, unlike some \"hot boxes\" where temperatures could top 100 degrees.  By the end of the 1920s, the Anaconda Company owned the Girl which operated until the 1950s.

Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>Elements are fundamental substances of matter - matter that is composed of the same types of atoms.  At present, 118 elements are known (four of them are still unnamed).  Of these, 98 occur naturally on Earth (hydrogen to californium).  Most of these occur in rocks & minerals, although some occur in very small, trace amounts.  Only some elements occur in their native elemental state as minerals.\n\u003C\u002Fp>\u003Cp>To find a native element in nature, it must be relatively non-reactive and there must be some concentration process.  Metallic, semimetallic (metalloid), and nonmetallic elements are known in their native state as minerals.\n\u003C\u002Fp>\u003Cp>Gold (Au) is the most prestigious metal known, but it's not the most valuable.  Gold is the only metal that has a deep, rich, metallic yellow color.  Almost all other metals are silvery-colored.  Gold is very rare in crustal rocks - it averages about 5 ppb (parts per billion).  Where gold has been concentrated, it occurs as wires, dendritic crystals, twisted sheets, octahedral crystals, and variably-shaped nuggets.  It most commonly occurs in hydrothermal quartz veins, disseminated in some contact- & hydrothermal-metamorphic rocks, and in placer deposits.  Placers are concentrations of heavy minerals in stream gravels or in cracks on bedrock-floored streams.  Gold has a high specific gravity (about 19), so it easily accumulates in placer deposits.  Its high density allows prospectors to readily collect placer gold by panning.\n\u003C\u002Fp>\u003Cp>In addition to its high density, gold has a high melting point (over 1000º C).  Gold is also relatively soft - about 2.5 to 3 on the Mohs Hardness Scale.  The use of pure gold or high-purity gold in jewelry is not desirable as it easily gets scratched.  The addition of other metals to gold to increase the hardness also alters the unique color of gold.  Gold jewelry made & sold in America doesn’t have the gorgeous rich color of high-purity gold.\n\u003C\u002Fp>\u003Cp>The largest gold mine in the Americas was the long-lived Homestake Mine in the town of Lead (pronounced “Leed”), South Dakota, USA.  Located in the Lead Window of the northern Black Hills Uplift in western South Dakota, the Homestake Mine produced about 40 million ounces of gold.  The gold at Homestake is almost exclusively confined to the Homestake Formation, a Paleoproterozoic (~1.9-2.0 billion years) sedimentary unit that originally consisted of interbedded Mg-rich siderite iron formation and marlstones.\n\u003C\u002Fp>\u003Cp>The Homestake Formation has been strongly deformed & multiply metamorphosed, and many of the original rocks were converted to greenschists (cummingtonite schists).  The gold has been interpreted as having been originally deposited with the iron formation sediments by seafloor volcanogenic exahalative processes.  Slight metamorphic gold mobilization and tight structural folding has resulted in the formation of auriferous greenschist pods along fold axes.\n\u003C\u002Fp>\nLocality: Main Ledge, 3050 Level, Homestake Mine, Lead, northern Black Hills, western South Dakota, USA",3994,2615,{"id":6737,"source_url":6738,"license_code":2015,"credit_html":6739,"title":6740,"description":6733,"author":2019,"original_width":2044,"original_height":6741},67511,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=39952362","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=39952362\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Gold and quartz (Main Ledge, 3050 Level, Homestake Mine, Lead, Black Hills, South Dakota, USA) 3 (17234822895).jpg",2399,{"id":6743,"source_url":6744,"license_code":2015,"credit_html":6745,"title":6746,"description":6733,"author":2019,"original_width":6747,"original_height":5048},67512,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=39952363","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=39952363\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Gold and quartz (Main Ledge, 3050 Level, Homestake Mine, Lead, Black Hills, South Dakota, USA) 2 (17027399647).jpg",3008,{"id":6749,"source_url":6750,"license_code":2015,"credit_html":6751,"title":6752,"description":6733,"author":2019,"original_width":6753,"original_height":6754},67513,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=39952368","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=39952368\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Gold and quartz (Main Ledge, 3050 Level, Homestake Mine, Lead, Black Hills, South Dakota, USA) 5 (17047268430).jpg",3992,2642,{"id":6756,"source_url":6757,"license_code":2015,"credit_html":6758,"title":6759,"description":6760,"author":2019,"original_width":6747,"original_height":5048},67524,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=87884951","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=87884951\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Gold and quartz (Main Ledge, 3050 Level, Homestake Mine, Lead, Black Hills, South Dakota, USA) 2.jpg","Gold and quartz from the Precambrian of South Dakota, USA.

The galenas are typical Neudorf style, extremely lustrous with sharp terminal faces and complex sides, sometimes in elongated crystals, here to 4 cm. This MAJOR German galena specimen was purchased by a prominent German collector from American dealer Rick Smith in 1970. This was the same era in which he was trading many old specimens out of the American Museum collections, and in any case it is certainly from an old source as this habit and style is characteristic of the most sought-after Neudorf specimens, from the mid to late 1800s. Such large, robust specimens are very hard to find today on the market. They ONLY come from major old collections, and the occasional museum deaccession. The piece is in remarkable condition with only trivial and peripheral edge wear, and one area near the bottom of broken galena (although it may simply be contacting and not true damage there as parts of that irregular area look crystallized on a micro scale). Even so, I have seen few CABINET sized examples of any quality; and we regard this as a major specimen.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",1382,{"id":7079,"source_url":7080,"license_code":1812,"credit_html":7081,"title":7082,"description":7083,"author":1862,"original_width":2289,"original_height":2290},71277,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=188116474","Slashme, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=188116474\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Whiteit Quarz Siderit 30869 2.jpg","Whiteite, quartz and Siderite from Yukon territory, Canada. 30 g",{"id":7085,"source_url":7086,"license_code":1812,"credit_html":7087,"title":7088,"description":7089,"author":1862,"original_width":2289,"original_height":2290},71278,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=188116475","Slashme, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=188116475\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Whiteit Quarz Siderit 30869 1.jpg","Whiteite, quartz and Siderite from Yukon territory, Canada. 30 g - mm scale",{"id":7091,"source_url":7092,"license_code":2371,"credit_html":7093,"title":7094,"description":7095,"author":7096,"original_width":7097,"original_height":7098},71899,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=2618565","Gia.cossa, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=2618565\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Fluorite-quarzo-ortoclasio.jpg","Fluorite-quarzo-ortoclasio from Cava Bianchi, Cuasso al Monte, Italy","Gia.cossa",2592,1944,{"id":7100,"source_url":7101,"license_code":2100,"credit_html":7102,"title":7103,"description":7104,"author":3212,"original_width":2105,"original_height":2044},72037,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=118205806","Pacific Museum of Earth from Canada, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=118205806\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Owyheeite with Quartz, Native Sulphur, and Pyrite (46995658235).jpg","\u003Cp>Near Hazelton\nBritish Columbia, Canada\n\u003C\u002Fp>\nS-74-1967",{"id":7106,"source_url":7107,"license_code":1718,"credit_html":7108,"title":7109,"description":7110,"author":1747,"original_width":2957,"original_height":1755},72465,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10125944","Robert M.

The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4.  Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens \"belong\" to each silicon.  The resulting formula for silica is thus SiO2, not SiO4.\n\u003C\u002Fp>\u003Cp>The simplest & most abundant silicate mineral in the Earth's crust is quartz (SiO2).  All other silicates have silica + impurities.  Many silicates have a significant percentage of aluminum (the aluminosilicates).\n\u003C\u002Fp>\u003Cp>Quartz (silicon dioxide\u002Fsilica - SiO2) is the most common mineral in the Earth's crust.  It is composed of the two most abundant elements in the crust - oxygen and silicon.  It has a glassy, nonmetallic luster, is commonly clearish to whitish to grayish in color, has a white streak, is quite hard (H≡7), forms hexagonal crystals, has no cleavage, and has conchoidal fracture.  Quartz can be any color: clear, white, gray, black, brown, pink, red, purple, blue, green, orange, etc.\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>From exhibit info.:\nAn included crystal occurs when a growing crystal completely engulfs an earlier-formed mineral.  The crystals trapped within the later crystal are then called inclusions within that crystal.  This quartz crystal has inclusions of blue papagoite.\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Papagoite is a bluish-colored calcium copper hydroxy-aluminosilicate mineral, CaCuAlSi2O6(OH)3.\n\u003C\u002Fp>\u003Cp>Locality: unrecorded\u002Fundisclosed site in Transvaal, South Africa\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Photo gallery of quartz:\n\u003C\u002Fp>\n<a href=\"\u003Ca rel=\"nofollow\" class=\"external free\" href=\"http:\u002F\u002Fwww.mindat.org\u002Fgallery.php?min=3337\">http:\u002F\u002Fwww.mindat.org\u002Fgallery.php?min=3337\u003C\u002Fa>\" rel=\"nofollow\">www.mindat.org\u002Fgallery.php?min=3337<\u002Fa>",1233,{"id":7181,"source_url":7182,"license_code":1718,"credit_html":7183,"title":7184,"description":7185,"author":1747,"original_width":1831,"original_height":1830},72687,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10124282","Robert M.

These alone would comand a pretty good price in such a miniature, with malachite of this quality. However, to cap it off, the malachite sets atop a rolling matrix of INTENSE BLUE quartz crystals, colored by shattuckite inclusions.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 5600 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The carbonate minerals all contain one or more carbonate (CO3-2) anions.\n\u003C\u002Fp>\u003Cp>Malachite and azurite are attractive, richly colored copper hydroxy-carbonate minerals.   Malachite has a nice green color - its formula is Cu2CO3(OH)2.  Azurite has a dark, rich blue color - its formula, Cu3(CO3)2(OH)2, is very close to malachite.  The blue color of azurite is from Cu+, while the green color of malachite is from Cu+2.  Azurite & malachite almost invariably occur together, and are telling indicators of copper in the field, even in very small quantities.  Blue azurite tends to crystallize first, and can convert to green malachite.  Some azurite-malachite specimens are solid enough to be cut and polished as semi-precious stone.\n\u003C\u002Fp>\u003Cp>The sample seen here is on an ore pile at the Continental Mine (= Continental Pit) in Butte, Montana.  The town is known as the “Richest Hill on Earth” and \"The Mining City\".  The Butte Mining District has produced gold, silver, copper, molybdenum, manganese, and other metals.\n\u003C\u002Fp>\u003Cp>The area's bedrock consists of the Butte Quartz Monzonite (a.k.a. Butte Pluton), which is part of the Boulder Batholith.  The Butte Quartz Monzonite (\"BQM\") formed 76.3 million years ago, during the mid-Campanian Stage in the Late Cretaceous.  BQM rocks have been intruded and altered by hydrothermal veins containing valuable metallic minerals - principally sulfides.  The copper mineralization has been dated to 62-66 million years ago, during the latest Maastrichtian Stage (latest Cretaceous) and Danian Stage (Early Paleocene).  In the supergene enrichment zone of the area, the original sulfide mineralogy has been altered.\n\u003C\u002Fp>\u003Cp>The Continental Mine targets a low-grade copper and molybdenum deposit on the eastern side of the Continental Fault, a major Basin & Range normal fault in the Butte area with about 3500 feet of offset.  The mine's rocks consists of disseminated copper sulfides plus copper- and molybdenum-bearing hydrothermal veins that intrude the BQM.  Minerals at the site include chalcopyrite, molybdenite, malachite, azurite, tenorite, and cuprite.  The latter four minerals are secondary copper minerals, produced by alteration of the primary copper sulfides.\n\u003C\u002Fp>\u003Cp>When I visited in 2010, the Continental Mine was making 50,000 to 52,000 tons of ore each day.  This mine can operate down to an ore grade of 0.1% copper.  Most of the mineralization is disseminated copper, but veins are also present.  Two stages of mineralization occurred in the Butte area - a porphyry copper system and a main stage system with large veins.  The bottom of the porphyry copper system is ~ less than 12,800 feet below the surface.  Veins peter out at 5600 to 5800 feet below the surface.  At the Continental Mine, veins are small - they're veinlets less than 6 inches wide.\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Photo gallery of malachite:\nwww.mindat.org\u002Fgallery.php?min=2550\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Photo gallery of azurite:\n\u003C\u002Fp>\nwww.mindat.org\u002Fgallery.php?min=447",3283,{"id":7808,"source_url":7809,"license_code":2015,"credit_html":7810,"title":7811,"description":7805,"author":2019,"original_width":7812,"original_height":5048},82338,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=99677208","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=99677208\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Azurite-malachite-tenorite in quartz monzonite (Continental Pit, Butte, Montana, USA) 8.jpg",2542,{"id":7814,"source_url":7815,"license_code":2100,"credit_html":7816,"title":7817,"description":7818,"author":3212,"original_width":2105,"original_height":2044},82439,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=118202811","Pacific Museum of Earth from Canada, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=118202811\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Gold in Quartz with Tetradymite (47814839281).jpg","\u003Cp>Red Mountain Mine, South of Sardis\nWashington, USA\n\u003C\u002Fp>\n\u003Col>\u003Cli>1118\u003C\u002Fli>\u003C\u002Fol>",{"id":7820,"source_url":7821,"license_code":1718,"credit_html":7822,"title":7823,"description":7824,"author":6373,"original_width":1395,"original_height":7825},82852,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=162904552","HolDu, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=162904552\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Tiemannit, Quarz.JPG","\u003Ca href=\"https:\u002F\u002Fen.wikipedia.org\u002Fwiki\u002FTiemannite\" class=\"extiw\" title=\"en:Tiemannite\">Tiemannite\u003C\u002Fa>, \u003Ca href=\"https:\u002F\u002Fen.wikipedia.org\u002Fwiki\u002FQuartz\" class=\"extiw\" title=\"en:Quartz\">Quartz\u003C\u002Fa>\n\u003Cdl>\u003Cdd>\u003Cdl>\u003Cdd>\u003Cdl>\u003Cdd>Weight: 69.3 g\u003C\u002Fdd>\n\u003Cdd>Locality: Charlotte Mine, Clausthal, Lower Saxony, Germany\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",2747,{"id":7827,"source_url":7828,"license_code":1718,"credit_html":7829,"title":7830,"description":7824,"author":6373,"original_width":3414,"original_height":6374},82853,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=162904578","HolDu, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=162904578\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Tiemannit, Quarz 2.JPG",{"id":7832,"source_url":7833,"license_code":2015,"credit_html":7834,"title":7835,"description":5707,"author":2019,"original_width":7836,"original_height":7837},82934,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=84500355","James St. John, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=84500355\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Tiger's eye quartz 4 (23829732706).jpg",2074,1445,{"id":7839,"source_url":7840,"license_code":1718,"credit_html":7841,"title":7842,"description":7843,"author":1747,"original_width":7627,"original_height":1930},83422,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10446119","Robert M.

Ancient Greeks called clear quartz **krystallos**, from *kruos* (\"icy cold\") and *stellein* (\"to contract\" or \"to solidify\"). They believed the mineral was a form of permanently solidified ice. The earliest recorded use of the name comes from Theophrastus, around 300–325 BCE[1]. Pliny the Elder carried the same belief into Roman natural philosophy, holding that quartz was ice permanently frozen after great lengths of time[2].\n\nThrough medieval Europe and the Middle East, the clear varietal was among the most commonly used materials for jewellery and hardstone carving[3]. It went by *rock crystal* in English, *Bergkristall* in German — names that preserved the older Greek root.\n\nThe modern name first appeared in print in 1505, in an anonymous mining tract from Freiberg, Saxony[4]. It was attributed to the physician Ulrich Rülein von Kalbe. A 20th-century hypothesis traces the German *quarz* to miners' vocabulary in the Erzgebirge ore region. Saxon miners called silver-bearing cross-veins **Querkluftertz** — *cross-vein-ore* — a clumsy word that condensed over generations into *Quertz* and finally *Quarz*[5].\\\nIn 1530, Georgius Agricola used both *quarzum* and *querze* in his Latin treatises, alongside competing names — *crystallum*, *silicum*, *silex* — drawn from older traditions[6]. The word took more than a century to settle.\n\nIn 1669, Nicolaus Steno obliquely formulated what would later be called the constancy of interfacial angles, in the caption of an illustration of quartz crystals[7].\\\nThe principle holds that a given mineral always crystallises with the same angles between its faces — a foundational law of crystallography.\n\nThe same year, Erasmus Bartholinus used variant spellings of *crystal* to mean species other than quartz, and any \"bodies with angles\" more broadly[8]. Only in the second half of the 18th century did *quartz* settle as the name for this particular mineral. By then, *crystal* had become a generic term for any body with angles[9].","claude-opus-4-7","1.7.0","2026-06-01 12:59:15",{"markdown":8859,"model_version":8855,"prompt_version":8856,"reviewed_at":8860},"Slice a synthetic quartz crystal thin, apply a voltage, and it vibrates at a fixed frequency. That property — piezoelectricity — makes quartz the timekeeper inside the small machines of daily life. Properly cut plates of quartz keep the frequency in radios, televisions, and electronic communications equipment, and the time in crystal-controlled clocks and watches[1]. The quartz clock — a clock built around a quartz oscillator — is one familiar example[2]. Almost all the quartz used this way is synthetic, grown by a hydrothermal process — a high-pressure heated-water bath — from natural-quartz feedstock[3].\n\nThe mineral's purest form goes into the silicon industry. High-purity quartz is the starting ore for the silicon used in chips and solar cells[4].\n\nVolume use looks different. Vast tonnages of quartz sand — silica sand — feed the glass and ceramics industries[5]. Fused quartz — the glass made by melting silica — is used in optics for its ability to transmit ultraviolet light[6].\n\nIndustrial sand has its own range of uses. Crushed quartz makes the abrasive grain on sandpaper[7]. Silica sand sets concrete, filters water, and — under the trade name *fracing sand* — props open the fractures that oil wells create deep underground[8].","2026-06-01 14:20:13"]
