{"product_id":"native-copper-64","title":"NATIVE COPPER","description":"Large chucky Native Copper crystals are a rarity worldwide, and even in the famous copper mines at Keweenaw, Michigan they are rare. The Central mine in Keweenaw Co. is one of the best-known mines to have produced them, but good examples always command a high price. This large miniature specimen from David Hardman's collection is in my view a really excellent demonstration of these large crystals. Although not complete all round, the crystal faces on display are all sharp and well-defined and present very well indeed. Individually, these crystals reach up to 1.8 cm across.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781413773647,"sku":"CC49564","price":444.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC49564_6ebe0199-3d81-4e61-b365-0037bd07e940.jpg?v=1783988471","url":"https:\/\/crystalclassics.co.uk\/products\/native-copper-64","provider":"Crystal Classics UK","version":"1.0","type":"link"}
