{"product_id":"tangdanite-3","title":"TANGDANITE","description":"Tangdanite is a relatively recently (2012) named mineral, closely related to Tyrolite with which it looks similar visually. Indeed, it was formerly known to collectors under the unofficial name of clinotyrolite as a calcium copper arsenate sulphate rather than a calcium copper arsenate carbonate. This toenail-sized massive Quartz matrix has the rare species Tangdanite forming a superb 1.3 cm diameter glossy pearlescent blue-green flat-lying disc-like spray. It comes from the Bartolomej mining field in Slovakia where the best examples of this new species have been found.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781363441999,"sku":"CC45728","price":104.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC45728_fdbdbc62-e131-4e70-a66b-c3fc33318b19.jpg?v=1783987335","url":"https:\/\/crystalclassics.co.uk\/products\/tangdanite-3","provider":"Crystal Classics UK","version":"1.0","type":"link"}
