{"product_id":"native-copper-with-cuprite","title":"NATIVE COPPER with CUPRITE","description":"A rich, crudely crystallised vuggy and porous mass of Native Copper is richly pervaded with octahedral Cuprite crystals, many showing complex modifications.  This old-time small cabinet specimen is from one of Cornwall's most famous mines, Wheal Unity in the parish of Gwennap, a little to the east of Redruth.  This specimen comes with a former collector's label and an Arnold Fisher Minerals stock label.  A thin plate of fragmented Quartz veinstone remains attached to the base.  The Native Copper has a uniform matt reddish chocolate brown patina whereas the Cuprite crystals are opaque maroon black.  Many of these will be translucent red if correctly backlit, but this is difficult to achieve.  A good example of Native Copper with Cuprite from Wheal Unity, a mine that worked the same wonderfully mineralised lode as Wheal Gorland.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46543050309807,"sku":"CC13092","price":550.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC13092.png?v=1770305025","url":"https:\/\/crystalclassics.com\/products\/native-copper-with-cuprite","provider":"Crystal Classics","version":"1.0","type":"link"}
