{"product_id":"acanthite-1","title":"ACANTHITE","description":"Rounded, metallic grey crystals of Acanthite measuring to 1.2 cm overgrow, and are partly embedded, in a matrix of crystalline Calcite from the old Gesegnete Bergmannshoffnung mine (closed around 1898) in Erzgebirge, Saxony, Germany. The Acanthite, a silver sulphide, forms rich crystallised mounds whose surfaces display rounded, rather hazy terminations and partial crystal faces; possibly ‘blurred’ by fluid-cutting by fast ground water-flow. The specimen is accompanied with an old German, beautifully handwritten label.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46540977471663,"sku":"CC7571","price":950.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC7571.png?v=1770221675","url":"https:\/\/crystalclassics.com\/products\/acanthite-1","provider":"Crystal Classics","version":"1.0","type":"link"}
