{"product_id":"calcite-with-duftite-3","title":"CALCITE   with DUFTITE","description":"This is a spectacularly large display specimen of colour-zoned rhombic Calcite crystals from the world-famous Tsumeb mine in Namibia. Aggregated together in a wonderfully eye-catching arrangement, the white to cream coloured Calcite crystals are aligned in a sweeping sculptural form with much to draw ones attention. The rare lead copper arsenate Duftite features also, as extensive thin khaki-green coatings on the back of the specimen and across some of the front-facing Calcite crystals. For such a large Calcite there is no obvious damage to be seen on the display surface. A really wonderful large display piece from Tsumeb. Ex Weyand collection.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781466792271,"sku":"CC53398","price":666.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC53398_55cc9d8a-7f33-4a4d-9f72-228dab39a4cd.jpg?v=1783989887","url":"https:\/\/crystalclassics.co.uk\/products\/calcite-with-duftite-3","provider":"Crystal Classics UK","version":"1.0","type":"link"}
