The pegmatites near the Lake George area of Colorado have produced what collectors and dealers know to be the finest Amazonite specimens from the standpoint of color, quality, wonderful display specimens and excellent associations. This large, sharp, lustrous, well-formed, rich blue-green color, prismatic Amazonite crystal is complete most of the way around, but does have some bruising on the back where it was obviously contacted due to tectonic activity underground. This specimen was collected over 30 years ago (June 1976), when Richard Kosnar found some of the finest color Amazonite from Colorado extant. This piece is completely unrepaired. Ex.

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 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>Feldspar is a group of common silicate minerals.  Feldspars are silicate minerals having one-fourth of all the silicons in SiO2 replaced by aluminum (Si4O8 to (Si3Al)O8).  When this happens, the (Si3Al)O8 has a -1 electric charge.  The charge is satisfied by the addition of one or more metals.  The (Si3Al)O8- structure has relatively large holes, and the only metals that tend to stay in these holes are: K (potassium), Na (sodium), Ca (calcium), Cs (cesium), Ba (barium), Sr (strontium), and Pb (lead).  Of these, K & Na & Ca are the most common metals that enter the matrix.  Sometimes, several different metals enter the structure, resulting in \"garbage can minerals\".\n\u003C\u002Fp>\u003Cp>Chemical analyses of feldspars show that they range in composition from K-feldspar to Na-feldspar and from Na-feldspar to Ca-feldspar.  Mineralogists have thus established two \"families\" of feldspars.  There is no chemical gradient between K-feldspar and Ca-feldspar.\n\u003C\u002Fp>\u003Cp>The potassium feldspars (K-feldspars) (also known as alkali feldspars) are those that range in composition from pure K-feldspar to pure Na-feldspar (actually, feldspars with ~even & random mixes of potassium and sodium are rare).  The feldspars with Na and\u002For Ca are the plagioclase feldspars.  All feldspars have similar physical properties: a hardness of about 6, a whitish streak, and two cleavage planes at or very near 90º.  Potassium feldspar is usually whitish to cream-colored to pinkish-orangish-salmon colored.\n\u003C\u002Fp>\u003Cp>\"Potassium feldspar\" refers to a group of several different K-rich minerals: orthoclase, microcline, adularia, sanidine, and anorthoclase.  Orthoclase, microcline, and adularia have the chemical formula KAlSi3O8 - potassium aluminosilicate.  Sanidine and anorthoclase have the formula (K,Na)AlSi3O8.\n\u003C\u002Fp>\u003Cp>Seen here is amazonite, a green-colored K-feldspar.  Specifically, amazonite is green microcline - it is known from several localities around the world.  Green orthoclase is also known, but is extremely rare - it was formerly only known from the Broken Hill Block in New South Wales, Australia (see: www.flickr.com\u002Fphotos\u002Fjsjgeology\u002F15120707951), but it's since been found elsewhere.

The link is almost certainly a misnomer. No deposit of this material has been confirmed along the Amazon, and it stays uncertain whether the green stones traded there were amazonite at all[1]. The name likely transferred from some other green stone of the region.\n\nThe mineral itself is not a separate species. It is the green to blue-green variety of microcline, a potassium feldspar — one of the rock-forming minerals built around potassium, aluminium and silica[2]. For many years the source of its colour was a puzzle. People assumed copper was responsible, since copper compounds are so often blue or green[3]. A 1985 study pointed instead to small amounts of lead and water held inside the feldspar, and later work added other trace elements to the picture[3].\n\nLong before any of this chemistry was understood, the stone was being worked. Amazonite has been used for jewellery for more than three thousand years, shown by finds in Middle and New Kingdom Egypt and in Mesopotamia[4]. In Bronze Age Egypt it was mined in the southern Eastern Desert, at Gebel Migif[5]. Curiously, despite this long working life, the stone is not mentioned by any ancient or medieval written source[4].\n\nIn early modern times the supply came almost entirely from one place — the area of Miass in the Ilmensky Mountains, about 80 kilometres southwest of Chelyabinsk in Russia, where it sits in granitic rock[5]. It was first described as a distinct mineral in the 18th century[4]. The formal name came later still: in 1847 the German mineralogist Johann Friedrich August Breithaupt named it for a type area he placed only vaguely, \"near\" the Amazon River[6]. Another classic source is Pikes Peak, in El Paso County, Colorado, where it occurs in coarse granite and pegmatite, the coarse-grained rock that fills late cracks in cooling magma[5].","claude-opus-4-8","1.7.0",{"markdown":416,"model_version":413,"prompt_version":414,"reviewed_at":8},"Amazonite is valued for its colour, not its chemistry. Its one practical use is ornamental: it is occasionally cut and worked as a gemstone[1]. Its modest hardness — enough to take a polish but soft enough to scratch — suits it to smooth, rounded cuts and polished pieces rather than the sharp facets cut into harder gems.\n\nIt has no industrial role of its own. As the green variety of microcline, it shares the makeup of common potassium feldspar, a rock-forming mineral of granite and pegmatite[2]. But amazonite is gathered for its blue-green appeal, not crushed and processed as bulk industrial feldspar. Beyond the lapidary bench, its main demand comes from mineral collectors, who prize good crystals as specimens."]
