{"product_id":"native-silver-with-native-copper-1","title":"NATIVE SILVER   with NATIVE COPPER","description":"This stunning cabinet-sized specimen from White Pine mine, Ontonagon County, Michigan, USA is an absolute treasure and a real rarity. Some of the most sought after specimens from the Michigan copper mining district are the crystallized Native Coppers, but of those, the ones with well-defined larger blocky crystals are amongst the rarest. Native Silver specimens are rare too, and highly collectible, but how often do you come across a combined Native Silver and Native Copper specimen with perfectly-formed large Native Copper crystals? Almost never, but not quite because this is one. Not only this, but it is very large and extremely presentable. The specimen shows fascinating detail: from hackly bright metallic Native Silver intergrown with bright metallic hackly native Copper; to the larger, well-defined smooth Native Copper crystals with a darker patina. A little white Quartz is also present. The Native Copper crystals reach 1.5 cm in length and although slightly rounded in form show crystal faces and growth-lines. This is a magnificent White Pine mine specimen of museum quality.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781203927375,"sku":"CC28049","price":9252.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC28049_d0d434e3-1b3f-43d2-87e2-5fe32128c70e.jpg?v=1783981694","url":"https:\/\/crystalclassics.co.uk\/products\/native-silver-with-native-copper-1","provider":"Crystal Classics UK","version":"1.0","type":"link"}
