Blister Copper","description":"Spherical crystals of Chalcopyrite up to 1 cm in diameter form a mound of Blister Copper from Tincroft mine in Illogan, a parish between Camborne and Redruth in Cornwall. The Blister Copper, a botryoidal variety of Chalcopyrite, is overgrown by 1 to 3 mm, slightly curved Chalcopyrite crystals and possibly some Siderite, all coated in a sooty black oxidation product. This is a rich representative specimen of Blister Copper from this most famous locality, once the very heart of the Cornish metalliferous mining industry.\n","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584163991727,"sku":"CC21581","price":250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC21581.png?v=1771846579","url":"https:\/\/crystalclassics.com\/products\/chalcopyrite-var-blister-copper-6","provider":"Crystal Classics","version":"1.0","type":"link"}
