{"product_id":"acanthite-with-native-silver-3","title":"ACANTHITE   with NATIVE SILVER","description":"An interesting combination of Rammelsbergite with Erythrite and Stephanite from Medenec in the Kru'n' Hory Mountains of Bohemia, Czech Republic.  The Rammelsbergite, a nickel arsenide, forms a roughly 4 x 2 cm dendritic porous mass of crystals, each averaging 1 mm, all of mid to light grey tin white with a micro-hackly texture.  The Rammelsbergite stands on a matrix of glassy Calcite forming a mound of tiny crystals at the front and a thin plate across the back.  A few individual spherules of crystallised bubble gum pink Erythrite are dusted over the specimen and along the interface between the Calcite and Rammelsbergite sit several small clusters of well-developed Stephanite crystals.  This small miniature is mounted vertically on a clear, colourless acrylic base.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545418256559,"sku":"CC28467","price":850.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC28467.png?v=1770390091","url":"https:\/\/crystalclassics.com\/products\/acanthite-with-native-silver-3","provider":"Crystal Classics","version":"1.0","type":"link"}
