{"product_id":"schaurteite-with-dolomite-in-germanite","title":"SCHAURTEITE with DOLOMITE  in GERMANITE","description":"Schaurteite is one of Tsumeb's unique secondary species, formed by the remarkably complex geochemistry of the deposit. Chemically, calcium germanium sulphate hydroxide hydrate, it formed through the oxidation of germanium- and sulphur-bearing Germanite in contact with calcium-bearing Dolomite\/Calcite. This large miniature specimen is mostly massive Germanite, but a vein of Dolomite\/Calcite within the centre contains patches of silky fibrous Schaurteite. In places, the vein reaches 18 mm wide, and the Schaurteite occurs in at least one patch 12 x 14 mm in area. A very rich matrix specimen of this extremely rare species, that allows its geochemical context to be understood. Rare indeed.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781193867599,"sku":"CC27619","price":2961.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC27619_11dc5c91-0903-472c-a7b7-e2c36fac2b56.jpg?v=1783981013","url":"https:\/\/crystalclassics.co.uk\/products\/schaurteite-with-dolomite-in-germanite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
