{"product_id":"calcite-with-dioptase","title":"CALCITE with DIOPTASE","description":"A highly lustrous mound of closely interpenetrating, snow-white rhombic Calcite crystals, averaging between 2 and 2.5 cm on edge overgrowing a hidden core of pinkish Calcite or Dolomite.  A splendid Calcite from the Tsumeb mine in Namibia, the faces of which are themselves covered in micro-rhombohedral crystals, all with a high lustre and intense buttermilk-white purity. Scattered over the specimen are five pinhead patches of micro-crystalline Dioptase which appear a more bluish green than usual because of their tiny size and the internal reflection of the underlying white Calcite.  A Calcite beautiful for its form, arrestingly buttermilk-white colour, and terrific lustre from Tsumeb.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780986937679,"sku":"CC17665","price":925.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC17665_03ce1364-4163-4f1d-9041-16b3d9af5cd9.jpg?v=1783973738","url":"https:\/\/crystalclassics.co.uk\/products\/calcite-with-dioptase","provider":"Crystal Classics UK","version":"1.0","type":"link"}
