{"product_id":"sphalerite-with-quartz-9","title":"SPHALERITE   with QUARTZ","description":"Intergrown flattish crystals of Sphalerite form a small plate with a dazzling metallic lustre and minor Quartz attached at both ends.  The specimen is from a somewhat obscure locality named Kranicher Gang, which worked the well documented Burgstatt veins close to the town of Clausthal-Zellerfeld in Lower Saxony, Germany.  The Sphalerite is iron rich and hence the crystals appear coal-black, but some areas, both on the top and base, grade to almost pure Sphalerite, of a beautiful translucent and tangy citrus yellowish-lime green.\n","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781027242319,"sku":"CC19643","price":333.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC19643_a74b8813-9fd2-4428-a475-9561c73a219a.jpg?v=1783976947","url":"https:\/\/crystalclassics.co.uk\/products\/sphalerite-with-quartz-9","provider":"Crystal Classics UK","version":"1.0","type":"link"}
