{"product_id":"native-copper-73","title":"NATIVE COPPER","description":"Tall and very dramatic is this branching dendritic Native Copper from Great Wheal Prosper in Cornwall. Reaching over 8 cm tall from where it rises up from its iron oxide-rich matrix, to over 10 cm wide, this is a very showy 'statement' piece. The Native Copper is infused with reddish Cuprite (copper oxide) and has a striking white coating in patches, which also extends over the whole front face of the matrix. This is a layer of silky acicular Aragonite or something similar. Ex Martin Kershaw Collection.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781469741391,"sku":"CC53992","price":888.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC53992_5023103f-2194-4011-93e3-c50c175de540.jpg?v=1783990061","url":"https:\/\/crystalclassics.co.uk\/products\/native-copper-73","provider":"Crystal Classics UK","version":"1.0","type":"link"}
