{"product_id":"cryolite","title":"CRYOLITE","description":"A superb, good-sized cabinet specimen of the sodium hexafluoroaluminate mineral Cryolite, from perhaps its most famous locality of the Ivigtut Cryolite Deposit at Ivittuut on Arsuk Fjord in Greenland.  This large tabular-shaped specimen is composed almost entirely of Cryolite apart from two 1.5 to 3 cm inclusions of dark and mid-chocolate-brown Siderite on the back face.  What sets this specimen apart from most Cryolite from this locality is that the almost the entire face is composed of glassy semi-transparent Cryolite crystals as stepped 0.5 cm cubes covering an area of 10 x 6 cm.  A remarkable and excellent crystallised Cryolite from Ivigtut.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781016363343,"sku":"CC19273","price":2591.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC19273_37e81974-d119-42c1-b60b-9e92c06ab9a9.jpg?v=1783975783","url":"https:\/\/crystalclassics.co.uk\/products\/cryolite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
