{"product_id":"wulfenite-with-serpierite-devilline","title":"WULFENITE   with SERPIERITE \/ DEVILLINE","description":"This is a very distinctive assemblage, or combination, of species, even by Tsumeb's standards. Brown, burnt-toffee coloured resinous shallow bipyramidal Wulfenite crystals, the largest reaching 6 mm on edge are liberally scattered across the uneven, black, pumice-like, weathered grey metallic sulphide matrix. However, unlike pumice, the density of this matrix unmasks its metallic constituents. Another clue is provided by bright pale turquoise-blue finely crystallized coatings of Serpierite\/Devilline. The Wulfenite crystals are extremely well-formed and a pleasure to view, with just a few showing slight chipping to their corners, which is extremely common for this fragile species. Ex Kessler Collection, the small typed accompanying label records \"Wulfenit Serpierit\/Devellin EDX Tsumeb Mine\". It is unclear which of these species, or if all, have been analysed by SEM energy dispersive X-ray analysis (EDX).","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781475836239,"sku":"CC55978","price":333.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC55978_edc423aa-2871-4029-afdb-7a38b10e4cb9.jpg?v=1783990367","url":"https:\/\/crystalclassics.co.uk\/products\/wulfenite-with-serpierite-devilline","provider":"Crystal Classics UK","version":"1.0","type":"link"}
