{"product_id":"dioptase-on-calcite-13","title":"DIOPTASE   on CALCITE","description":"An iconic combination from the world-famous Tsumeb mine: Dioptase on Calcite. Dioptase from Tsumeb mine is generally regarded as the world's best: not so much on size - although crystals are large - but because of their exceptionally bright glassy lustre, and their combinations with contrasting pale coloured Calcite. This lovely miniature specimen shows this perfectly, with supremely glossy intense emerald-green Dioptase crystals to over 1 cm in length sat gracefully upon a pale cream coloured Calcite base. The Dioptase crystals are extremely well-formed with only very minor edge-wear apart from a fractured crystal on one edge. This might be a miniature, but it is really pretty and a cute Tsumeb Dioptase.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781363081551,"sku":"CC45640","price":925.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC45640.jpg?v=1784023093","url":"https:\/\/crystalclassics.co.uk\/products\/dioptase-on-calcite-13","provider":"Crystal Classics UK","version":"1.0","type":"link"}
