{"product_id":"calcite-with-chalcopyrite-section","title":"CALCITE with CHALCOPYRITE Section","description":"Black Ox mine is one of Derbyshire's lesser-known mineral localities, situated only about 1 km to the southwest of Matlock and a little north of Masson Hill, both familiar names in the world of mineralogy.  From Black Ox we have an unusual 1.6 cm thick, cleaved block of Calcite displaying a pale honey yellow translucent to semi-transparent outer crust with a large area of transparent, colourless Calcite surrounded distinct darkened zones of included micro-crystals of brassy Chalcopyrite.  A most fascinating and unusual Derbyshire specimen.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584064966831,"sku":"CC17244","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC17244.png?v=1771843814","url":"https:\/\/crystalclassics.com\/products\/calcite-with-chalcopyrite-section","provider":"Crystal Classics","version":"1.0","type":"link"}
