{"product_id":"sphalerite-with-quartz-1","title":"SPHALERITE with QUARTZ","description":"This fine cabinet specimen is typical of specimens that came out of Wheal Jane during its revived period of operation during the 1970’s and 80’s until closure.  A heavy matrix of cryptocrystalline grey and white Quartz containing disseminated Pyrite and Chalcopyrite is richly coated with colourless to grey-white, well-developed and terminated Quartz crystals together with compound crystals of inky-black Sphalerite.  Set against a greenish-grey chloritized crust which covers the matrix, the Quartz crystals are developed to over 2 cm long in diverse orientations. The Sphalerite varies from equant individual crystals to complex groups, one group being dusted with micro-crystals of Pyrite.  A great and characteristic specimen from Wheal Jane at Baldhu, close to the city of Truro in Cornwall, England.\n","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46542957445295,"sku":"CC10312","price":950.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC10312.png?v=1770296174","url":"https:\/\/crystalclassics.com\/products\/sphalerite-with-quartz-1","provider":"Crystal Classics","version":"1.0","type":"link"}
