{"product_id":"siderite-6","title":"SIDERITE","description":"Despite being an iron carbonate, the density of Siderite has never really struck me until lifting this pure and remarkably fine cabinet specimen, with a specific gravity 3.96. This is an outstanding, smack-you-in-the-chops large cabinet specimen composed entirely of lustrous Siderite crystals forming gently curved rhombic prisms. The crystals average around 1.5 cm on edge yet do attain 2 cm. From Hüttenberg in Carinthia, Austria, the Siderite crystals are opaque with a translucent outer shell and are a fairly uniform golden biscuit deep tan, like a digestive biscuit spread with syrup! Examined close to with a low power lens, the stacked curved and slightly offset corners make good analogies of the roof of the Sidney Opera House. This museum quality specimen that will look magnificent displayed.\n","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781171192143,"sku":"CC25212","price":5921.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC25212_939c5f13-ef23-4164-9967-cf84fb8843fb.jpg?v=1783980053","url":"https:\/\/crystalclassics.co.uk\/products\/siderite-6","provider":"Crystal Classics UK","version":"1.0","type":"link"}
