{"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":46545406853295,"sku":"CC28049","price":12500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC28049.png?v=1770389492","url":"https:\/\/crystalclassics.com\/products\/native-silver-with-native-copper-1","provider":"Crystal Classics","version":"1.0","type":"link"}
