{"product_id":"chalcophyllite","title":"CHALCOPHYLLITE","description":"A very richly crystallized large miniature specimen of the rare hydrated copper aluminium arsenate sulphate hydroxide mineral, Chalcophyllite from Wheal Gorland, St. Day, Cornwall. 2\/3 of the main display surface is covered in pearlescent, blue-green platy Chalcophyllite crystals and this extends around the edges of the specimen too. These small (to 2 mm) hexagonal platy crystals line cavities and form intergrown masses within a Goethite gossan with some remnant Chalcopyrite.  The largest Chalcophyllite crystal-lined cavity, is 2.8 x 1.5 cm. As Cornish Chalcophyllite specimens go, this one is very rich.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781503394127,"sku":"CC7455","price":1850.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC7455_bef11d41-635b-48af-bc57-dd0c34b08b84.jpg?v=1783991799","url":"https:\/\/crystalclassics.co.uk\/products\/chalcophyllite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
