{"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":46709987508399,"sku":"CC45728","price":140.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC45728.png?v=1774628284","url":"https:\/\/crystalclassics.com\/products\/tangdanite-3","provider":"Crystal Classics","version":"1.0","type":"link"}
