{"product_id":"bornite-with-calcite-and-quartz","title":"BORNITE with CALCITE  and QUARTZ","description":"Good Bornite crystals are not common and this specimen displays a fine example as a single 1.5 x 1 x 1 cm compound crystal covered in scaley faces with a characteristic metallic iridescence of peacock blue, reddish-purple and gold. This fine crystal sits against a 4 cm long crude scalenohedral Calcite coated in brassy iridescent micro-crystals of Pyrite on top of a matrix of crystallised glassy Quartz.  The Calcite is double terminated, although the tip of its upper termination is slightly cleaved.  A lovely miniature from the Dzhezkazgan mining district in the Karaganda Region of Kazakhstan.  The specimen comes mounted on a square clear acrylic base.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781019246927,"sku":"CC19402","price":518.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC19402_28e39eb4-be47-44b7-8c19-cb50bcb333b5.jpg?v=1783976361","url":"https:\/\/crystalclassics.co.uk\/products\/bornite-with-calcite-and-quartz","provider":"Crystal Classics UK","version":"1.0","type":"link"}
