{"product_id":"native-copper-28","title":"NATIVE COPPER","description":"A simple 'Y-shape' structured specimen of beautiful, arborescent branching Native Copper crystals.  This splendid ex-matrix specimen is from the Rubtsovskoe Cu-Zn-Pb deposit at Rudnyi Altai in the Western Siberian Region of Russia.  Individual crystals grow to well over 1 cm in length and may easily reach 2 cm.  It is difficult to estimate where one crystal ends and another begins, hence a little leeway in their maximum length.  The Native Copper has a gorgeous bronze-milk chocolate patina, as all the best Copper specimens do, and a slightly waxy, metallic lustre.  An excellent example of nicely crystallised Native Copper.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781010956623,"sku":"CC18944","price":2591.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC18944_590fc74e-e863-4814-b04e-ea29986da5a6.jpg?v=1783975458","url":"https:\/\/crystalclassics.co.uk\/products\/native-copper-28","provider":"Crystal Classics UK","version":"1.0","type":"link"}
