{"product_id":"siderite-15","title":"SIDERITE","description":"Although Siderite is a relatively common mineral at Tsumeb, occurring in each of the three oxidation zones, specimens are not that often seen in collections because aesthetic specimens tend to be very rare.  A 2.2 cm by 0.5 to 1.0 cm wide patch of well crystallised, gemmy-brownish-yellow Siderite sits on a germanium-rich sulphide matrix with a play of peacock-blue iridescence.  A few Siderite crystals measure to 5 mm long with good terminations.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780962951503,"sku":"CC15896","price":222.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC15896_03c29bd9-4e26-4636-99e4-ebdcb699a970.jpg?v=1783972259","url":"https:\/\/crystalclassics.co.uk\/products\/siderite-15","provider":"Crystal Classics UK","version":"1.0","type":"link"}
