{"product_id":"ferberite-4","title":"FERBERITE","description":"Not so long ago we used to refer to Ferberite as Wolframite, but those simpler days are now gone!  Ferberite is the iron (Fe) end-member of the manganese-iron wolframite solid solution series, the Mn end being H'bnerite.  This delightful large thumbnail has a 1.9 x 0.9 x 0.3 cm black Ferberite bladed crystal, with a bright reflective metallic lustre, standing vertical on a mixed Galena and Pyrite matrix coated with snow-white Calcite crystals.  The Calcites are themselves superb, forming individual, highly distorted and flattened rhombohedrons, which stack to create vermiform (worm-shaped) chains which criss-cross the matrix's surface.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545176658095,"sku":"CC20231","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC20231.png?v=1770375903","url":"https:\/\/crystalclassics.com\/products\/ferberite-4","provider":"Crystal Classics","version":"1.0","type":"link"}
