{"product_id":"ferberite-after-scheelite-with-scheelite","title":"FERBERITE after SCHEELITE with SCHEELITE","description":"A rarity from the Drakelands mine (formerly Hemerdon mine and Hemerdon Bal) at Sparkwell in south Devon.  A single pyramidal Scheelite crystal measuring to 6 mm is replaced by metallic black Ferberite, the iron-rich end member of the Ferberite-Hübnerite Series, formerly and more simply known as Wolframite. This sits on a matrix of white Quartz with micro-crystal druses of Ferberite and rare yellow crystallised areas of probable Hydrokenoelsmoreite, a hydrous tungsten oxide. Some reddish iron stained Kaolinite is also apparent. A great and unusual small miniature from, and adhering to the most recognised of all its various locality names, Hemerdon.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781465219407,"sku":"CC5312","price":259.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC5312_84905190-b908-4d12-b415-8ece5352a81d.jpg?v=1783989811","url":"https:\/\/crystalclassics.co.uk\/products\/ferberite-after-scheelite-with-scheelite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
