{"product_id":"duftite-with-dioptase-on-calcite-1","title":"DUFTITE with DIOPTASE  on CALCITE","description":"This cabinet specimen from Tsumeb displays the classic association of murky, pale camouflage-green Duftite coating rhombic Calcite crystals. The Calcite crystals are opaque white and exceptionally reach 1.6 cm on edge, but most average 1 cm. Many contain extremely fine-grained pale emerald green Dioptase inclusions within their outermost layer with the finely crystallized Duftite preferentially favouring certain crystal faces on the Calcite, leaving others fresh. A second, later phase of tiny rhombic Calcite microcrystals are scattered upon the Duftite. A fine displayable classic from Tsumeb.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781364588879,"sku":"CC46114","price":888.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC46114_65fc8d64-63fc-4856-a43a-8e3a009c37e0.jpg?v=1783987396","url":"https:\/\/crystalclassics.co.uk\/products\/duftite-with-dioptase-on-calcite-1","provider":"Crystal Classics UK","version":"1.0","type":"link"}
