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>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>Silver is part of the gold-group of metallic elements.  Silver is a precious metal, but is far less valuable than gold or platinum.  Silver usually occurs as a silver sulfide mineral, but it also occurs in nature in its native state, often in the form of twisted wires.  Silver is moderately soft and has a silvery-white color on fresh surfaces that tarnishes to darker colors.  Elemental silver in nature is often found alloyed with other metals.  Naturally alloyed gold-silver is called electrum.\n\u003C\u002Fp>\nLocality: La Nevada Mine, Batopilas District, Chihuahua State, northern Mexico","James St. John",2458,1167,{"id":415,"source_url":416,"license_code":417,"credit_html":418,"title":419,"description":420,"author":421,"original_width":422,"original_height":422},69816,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=28857902","CC BY 3.0","Hi-Res Images of Chemical Elements, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=28857902\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Pieces of silver, 3 grams, the biggest piece is 1 cm long.jpg","Pieces of silver, 3 grams, the biggest piece is 1 cm long.","Hi-Res Images of Chemical Elements",900,{"id":424,"source_url":425,"license_code":397,"credit_html":426,"title":427,"description":428,"author":429,"original_width":430,"original_height":431},17323,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=150714014","Robert M.

This piece has a beautiful dark patina caused by a micro layer of acanthite coating, and an exquisite complexity to the rope as it twists and turns like a living thing. The piece is VERY sturdy despite its elegant look, and this is a solid piece that is not flexible or \"bendy\" like some German silvers of this size. Long one of the premier silvers in the Meieran collection, and one of the half dozen best he had acquired through buying and trading over the last 50 years of trying to assemble one of the best suites of native elements. I feel that the price here is a downright bargain, all things considered; as well as compared to numerous pieces I have seen for sale in the same price range in only the last year that simply do not blow me away as this one does (heck, I have seen a dozen so-called six-figure silvers at Springfield Show alone, and they couldn't touch this with a ten foot pole for impact !). Because of the size and quality of this specimen, I was happy to have the privilege of trading this from Gene only recently. Gene told me the following as well: The one you got was originally from Wayne Thompson to Evan Jones then to me, if I remember. Exchanged for ALL my Mexican and Arizona minerals.

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>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>Silver is part of the gold-group of metallic elements.  Silver is a precious metal, but is far less valuable than gold or platinum.  Silver usually occurs as a silver sulfide mineral, but it also occurs in nature in its native state, often in the form of twisted wires.  Silver is moderately soft and has a silvery-white color on fresh surfaces that tarnishes to darker colors.  Elemental silver in nature is often found alloyed with other metals.  Naturally alloyed gold-silver is called electrum.\n\u003C\u002Fp>\nLocality: Silverfields Mine, Cobalt, Ontario, Canada",2838,1861,{"id":651,"source_url":652,"license_code":585,"credit_html":653,"title":654,"description":655,"author":589,"original_width":656,"original_height":657},17141,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=163479957","Darla Sondrol, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=163479957\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Native silver (GeoDIL number - 883).jpg","This specimen contains native silver (tarnished gray) in a quartz matrix.

Sometimes it grows on its own — as a wire, a tangled mass, or a tree-shaped sprig of pure metal in a crack of rock. That is native silver, and for most of human history it was the easiest way to lay hands on the element.\n\nThe English name traces back to the Old English *seolfor*, whose deeper meaning has been lost[1]. The modern spelling *silver* is recorded by 1478[2]. The chemical symbol Ag comes from a parallel line — the Latin *argentum*, the Romans' name for the metal[3]. *Argentum* itself reaches further back, to a Proto-Indo-European root meaning \"white\" or \"shining\"[4].\n\nWorked silver appears alongside copper and gold in the earliest metalwork. From the 4th millennium BCE the metal was used for ornamental and utilitarian purposes in Anatolia and the Aegean[5]. Silver ornaments and decorations have been found in royal tombs dating back as far as 4000 BCE[6]. In Ancient Egypt the metal was associated with the moon and ritual purity[7]. Some of that material was picked up as native silver; much of it was already being separated from gold by heating the two metals with salt and reducing the silver chloride to the metal[8].\n\nBy the 7th century BCE the Greeks had moved well past the easy nuggets. They were extracting silver from galena — a heavy lead sulfide that yields silver as a side product[9]. The rise of Athens was funded by the mines at Laurium, which produced about 30 tonnes a year between 600 and 300 BCE[10]. Rome later industrialised the same trade. At peak production it drew about 200 tonnes a year, mostly from Spain[11]. By that point native silver was a small slice of supply; the bulk of the metal was being smelted out of base-metal ores.\n\nCentral Europe became the centre of silver production during the Middle Ages, after the Mediterranean deposits had been exhausted[12]. New mines opened in Bohemia, Saxony, Alsace, Hungary, Norway, the southern Black Forest and elsewhere[12]. **Freiberg**, in the Saxon Erzgebirge, produced spectacular dendritic and arborescent silver associated with proustite and stephanite — two silver-bearing sulphide minerals — under the eye of the first European mineralogists[13].\n\nSpanish exploitation of the Americas then displaced the European mines in scale. In 1554 Bartolomé de Medina developed the **patio process** in Pachuca, in Mexico, allowing efficient extraction of silver from low-grade ores by amalgamation with mercury[14]. The technique revolutionised production and made Peru, Bolivia, Chile and Argentina the dominant silver producers from the 17th century onward[15]. Most of that colonial silver was smelted from sulphide ores, but a handful of Mexican districts — **Batopilas** in Chihuahua among them, famed for herringbone dendrites of native silver in white calcite — yielded extraordinary native specimens alongside the bulk production[16].\n\nThe next great native-silver district was Norwegian. Mining at **Kongsberg** ran from 1623 to 1958 in vein systems where hydrothermal fluids reacted with carbonaceous sedimentary beds, creating localised reducing conditions that grew the metal into wires[17]. The wires — twisted, curled, sometimes a metre long — made Kongsberg specimens the standard against which every later wire-silver find is measured.\n\nNorth America added its own districts in the 19th and early 20th centuries. The **Comstock Lode** in Nevada, discovered in 1859, was the first major silver rush in the United States; its bonanza veins held native silver intergrown with argentite (silver sulphide) and electrum, a natural gold-silver alloy[18]. The **Cobalt** district of Ontario, discovered in 1903, produced slabs of native silver associated with skutterudite and smaltite — cobalt-nickel-arsenide minerals that gave the town its name[19].","claude-opus-4-7","1.7.0",{"markdown":1335,"model_version":1332,"prompt_version":1333,"reviewed_at":11},"Almost none of the silver in the world economy began life as native silver. Over 80% of global silver supply is a by-product of smelting polymetallic sulfide ores — the lead-zinc-copper-gold concentrates from which silver is recovered downstream[1]. Native silver itself, the wires and dendrites and tree-shaped sprigs of pure metal occasionally pulled from veins, constitutes only a minor fraction of global production[2]. The mineral is mostly a specimen today; the element it is made of, by contrast, is one of the most heavily worked industrial substances on Earth.\n\nThe specimen market is what keeps the mineral in circulation. Well-preserved historical native silver is rare because crystalline and wire forms were routinely melted into bullion for export when they came out of the ground[3]. The pieces that survive — Kongsberg wires, Cobalt slabs, Batopilas dendrites — sit in museum collections and serious mineral cabinets, and they are valued well above their weight in metal.\n\nThe element itself flows through industry in roughly the proportions the 2024 figures record. In the United States, the estimated end-use breakdown was physical investment (bars) 30%, electrical and electronics 29%, coins and medals 12%, photovoltaics 12%, jewellery and silverware 6%, brazing and solder 4%, and other industrial uses and photography 7%[4]. Industrial demand alone reached a record 680.5 million ounces in 2024, the fourth consecutive year at a new high[5].\n\n### In electronics and solar\n\nSilver is the most electrically conductive metal known at room temperature, with a conductivity of 6.30 × 10⁷ S\u002Fm[6]. That single property is what carries it into almost every electronic circuit at some scale — switch contacts, conductive pastes, plated connectors, thick-film hybrids — and into the silver-bearing paste printed on every crystalline-silicon solar cell to collect the photo-generated current.\\\nThe photovoltaic share has grown faster than any other. Solar consumption of silver rose from 59.6 million ounces in 2015 to about 232 million ounces in 2024[7]. Within the industrial subtotal, photovoltaics already account for nearly a third of demand[7], and growth in that segment is driving most of the recent overall increase in industrial silver use[5].\n\n### In objects, coins, and medicine\n\nJewellery and silverware draw the next-largest slice. In 2024 silver jewellery fabrication grew 3% to 208.7 million ounces, while silverware demand fell 2% to 54.2 million ounces — a three-year low[5]. Coinage and bullion together still take a comparable share, both as monetary instruments and as the most common form in which the metal is held as an investment[4].\n\nBrazing alloys take another slice. These are silver-bearing fillers used to join metal parts at temperatures above 450 °C, well below the melting points of the parts themselves. Demand for the alloys grew 3% in 2024 on the back of automotive and aerospace work[5]. Medical use is a smaller stream — mostly silver nitrate and other silver compounds added to bandages, wound dressings, catheters and other instruments as disinfectants and microbiocides[8]. The same silver-halide chemistry also underlies light-darkening glass — the photochromic lens material used in spectacles that tint in sunlight[9].\n\nTwo visible uses are quietly contracting. Photography, once the single largest end-use of silver because of silver-halide film, has been displaced by digital imaging and now sits inside the residual \"other industrial and photography\" 7% slice[4]. Silverware fabrication is declining for similar consumer-preference reasons[5].\n\nDemand has now outrun mine and recycle supply for four years running, leaving the market in a structural deficit of 148.9 million ounces in 2024[5]. None of that flow runs through native silver in any quantitative way — the mineral's role is now almost entirely cultural, in museum cabinets and serious collections, while the work of supplying the element is done by sulfide concentrates fed into the world's smelters[1]."]
