{"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":46545157324975,"sku":"CC18944","price":3500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC18944.png?v=1770374482","url":"https:\/\/crystalclassics.com\/products\/native-copper-28","provider":"Crystal Classics","version":"1.0","type":"link"}
