The Native Copper forms a spongy pisolitic porous mass with micro-botryoidal concretionary crystallised grains and hackly fronds and branches.  Some patches of white granular Quartz lurk within the Copper structure.  A fine example from the famous St. Just mines.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780842791247,"sku":"CC13514","price":444.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC13514.png?v=1779743828","url":"https:\/\/crystalclassics.co.uk\/products\/native-copper-21","provider":"Crystal Classics UK","version":"1.0","type":"link"}
