{"product_id":"cronstedtite-2","title":"CRONSTEDTITE","description":"Cronstedtite, a complex iron silicate, is one of the classic minerals associated with Wheal Jane at Baldhu, between Redruth and the city of Truro in Cornwall.  The Cronstedtite forms triangular crystals, 1 to 2 mm across, jet-black with a bright reflective lustre.  They richly cover a 5 x 1.5 cm surface of grey Killas matrix.  Tiny deep tan Siderite crystals forming botryoidal mounds are also present.  It's a fine and rich example of the rare mineral Cronstedtite, from Wheal Jane.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46543058993327,"sku":"CC13505","price":1000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC13505.png?v=1770305662","url":"https:\/\/crystalclassics.com\/products\/cronstedtite-2","provider":"Crystal Classics","version":"1.0","type":"link"}
