{"product_id":"chalcophyllite-8","title":"CHALCOPHYLLITE","description":"A fine small miniature of turquoise green Chalcophyllite crystals lining two vugs in a grey and tan, iron-stained granite matrix from Wheal Gorland, then part of the St. Day United Mines in Gwennap, Cornwall.  The Chalcophyllite forms well-defined hexagonal platy crystals of 1 to 2 mm diameter and also pervades the matrix where sub-mm crystals line intergranular void space.  The specimen comes with three previous labels: a private German collection; Paul A. Lowe (Truro) stock label and a very neatly written University of Pennsylvania label.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584042815663,"sku":"CC12810","price":275.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC12810.png?v=1771841099","url":"https:\/\/crystalclassics.com\/products\/chalcophyllite-8","provider":"Crystal Classics","version":"1.0","type":"link"}
