Note: A Bolivian pyrargyrite is much more uncommon and likely to be older as well, than seemingly similar material from Mexico. These specimens turn up only rarely and from very old collections. I believe they were collected prior to the 1940s, and some would date back far earlier still to the late 1800s (as I have seen them turn up in some very old collections such as G.J. Brush’s at Yale).

It is a large and very rich specimen for this rare silver species! The crystals are to 1 mm (though most are smaller than that and are sparkly sub-mm crystals), and although the species gets bigger it is but rarely and seldom in any large clusters as we see here. There are literally hundreds of crystals here and the piece could easily be chopped in portions for sale at higher prices in total.

The German mining scholar Georg Agricola mentioned it in 1546[1]. But the name covered two different minerals that look almost identical. They were not told apart until chemists analysed both and found one held antimony where the other held arsenic[1].\n\nThe antimony one is pyrargyrite. Its name was coined in 1831 from two Greek words — *pyr*, fire, and *argyros*, silver. It means \"fire-silver\", a nod to both its deep red colour and the silver locked inside it[2]. Large crystals look greyish-black and opaque, but hold a thin sliver to the light and it glows ruby-red[3].\n\nIts near-twin is proustite, the arsenic version of the same mineral — \"light red silver ore\" to pyrargyrite's \"dark red silver ore\". The two share the same crystal form yet rarely blend[4]. The quickest way to separate them is the streak, the colour of the powder a mineral leaves when scraped. Pyrargyrite streaks purplish-red; proustite streaks a brighter scarlet[4].\n\nThe finest crystals came from the old silver-mining heartlands — Sankt Andreasberg in the Harz mountains, Freiberg in Saxony, and Guanajuato in Mexico[5]. Spanish mines at Guadalcanal and Hiendelaencina yielded specimens of unusual quality[5]. In the United States the mineral turned up at Silver City in Idaho and was abundant at the Comstock Lode in Nevada[6].","claude-opus-4-8","1.0.0",{"markdown":539,"model_version":536,"prompt_version":537,"reviewed_at":11},"Pyrargyrite is mined for one thing: the silver bound up inside it. The mineral is a source of silver, not of the antimony it also contains[1]. Where it occurs in quantity, smelters recover the silver and leave the antimony aside.\n\nToday that role is small. Pyrargyrite turns up in scattered amounts in silver veins rather than in the massive deposits that feed modern silver supply — it is common in only small amounts even in the silver mines of the western United States[2]. The metal the world uses for coins, electronics and solar cells comes mostly from other, more abundant silver minerals and from the refining of lead, zinc and copper ores.\n\nWhat demand the mineral still draws is mostly from collectors. Well-formed crystals — dark and metallic in bulk, glowing deep ruby-red where light passes through a thin edge[3] — are sought as display specimens, especially the prized old-locality material from Sankt Andreasberg, Freiberg and Guanajuato[4]."]
