{"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":46540961415343,"sku":"CC7455","price":2500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC7455.png?v=1770220793","url":"https:\/\/crystalclassics.com\/products\/chalcophyllite","provider":"Crystal Classics","version":"1.0","type":"link"}
