{"product_id":"dioptase-with-calcite-2","title":"DIOPTASE   with CALCITE","description":"For its richness in Dioptase crystals this is a extremely fine miniature specimen. It is from the undisputed king of Dioptase occurrences at Tsumeb mine in Namibia. Comprising a white Calcite crystal-coated matrix, extremely bright, gemmy, emerald-green Dioptase crystals completely cover the display surface hiding the Calcite from view. These Dioptase crystals are, at up to 8 mm in length, not the world's largest, but are all undamaged and show wonderfully sharp crystal form. A couple of small areas of later Calcite sit upon the Dioptase adding nice flashes of contrasting colour, but it is the exceptional gem-bright appearance of the Dioptase which sets this specimen apart.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781258092879,"sku":"CC34682","price":3701.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC34682_4694e552-cb48-4c84-b99e-effe0662162b.jpg?v=1783984247","url":"https:\/\/crystalclassics.co.uk\/products\/dioptase-with-calcite-2","provider":"Crystal Classics UK","version":"1.0","type":"link"}
