{"product_id":"ferberite-3","title":"FERBERITE","description":"This rather lovely ex-matrix crystal of Ferberite is from the tin deposit at C'novec\/Zinnwald near to Erzgebirge and Krusn' Hory, an orebody which spans the border between Germany (Saxony) and the Czech Republic (Bohemia), hence its double-name.  Ferberite is what used to be named Wolframite, but now specifically defines the iron-end member of the Ferberite-H'bnerite iron-manganese tungstate series.  The metallic greyish-black crystal forms a 4.0 x 5.8 x 1.7 cm chisel-like blade with a 3 cm long sharp termination with stepped and horizontally striated prism faces.  An excellent Ferberite crystal from the famous and classic C'novec\/Zinnwald deposit.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545169121455,"sku":"CC19702","price":600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC19702.png?v=1770375426","url":"https:\/\/crystalclassics.com\/products\/ferberite-3","provider":"Crystal Classics","version":"1.0","type":"link"}
