{"product_id":"native-copper-72","title":"NATIVE COPPER","description":"This is a rather sculptural crystallized Native Copper from the famous copper mines at Bisbee, Warren District, Cochise County, Arizona, USA. Highly elongated sharply-tipped spinel-twinned Native Copper crystals protrude into cavities towards the centre of a quite open-textured pure aggregate of Native Copper. Some interlock like a birds nest, but the outer edge of the specimen on one side is more compact. These crystals reach up to 9 mm in length, with most 7 to 8 mm on average. There is minor pale green powdery alteration on the surface of the Native Copper within recessed pockets in the more compact areas, but the crystals are clean and show a very fine rich orange colour and good metallic lustre. A wonderfully characterful Arizonan Native Copper.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781459812687,"sku":"CC52022","price":3701.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC52022_011c2a63-6b48-4487-9858-ab3b80cc72c7.jpg?v=1783989539","url":"https:\/\/crystalclassics.co.uk\/products\/native-copper-72","provider":"Crystal Classics UK","version":"1.0","type":"link"}
