{"product_id":"dioptase-17","title":"DIOPTASE","description":"Of all Tsumeb's spectacular minerals, the copper silicate Dioptase is widely considered its signature species.  Dioptase is much loved by collectors for its emerald-like colour and Tsumeb has produced some of the world's best.  This charming small miniature has a completely hidden core of creamy-tan Dolomite, encrusted with glassy lustrous Dioptase crystals up to 1 cm across.  Their colour is that of deep and rich emerald-green; the outer zones being transparent with inner translucent centres.  The crystal centres reflect light from internal planes, giving an inner glow of electric emerald-green and amazing variations in colour.  Superb!","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781129937231,"sku":"CC20533","price":925.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC20533_492fe947-e228-4f27-82b0-3d18728935dd.jpg?v=1783978573","url":"https:\/\/crystalclassics.co.uk\/products\/dioptase-17","provider":"Crystal Classics UK","version":"1.0","type":"link"}
