{"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":46549974286511,"sku":"CC53398","price":900.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC53398.png?v=1770655558","url":"https:\/\/crystalclassics.com\/products\/calcite-with-duftite-3","provider":"Crystal Classics","version":"1.0","type":"link"}
