{"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":57781505261903,"sku":"CC7571","price":703.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC7571_7cf9cf7d-f68f-4d93-8594-2de5495bd1aa.jpg?v=1783991909","url":"https:\/\/crystalclassics.co.uk\/products\/acanthite-1","provider":"Crystal Classics UK","version":"1.0","type":"link"}
