{"product_id":"siderite-with-calcite-1","title":"SIDERITE with CALCITE","description":"This Siderite, from the P?'bram District in the Czech Republic, forms an almost circular, slightly domed specimen, covered with broad, gently curving blades, typically 2 cm across and of a characteristic honey-tan.  This colour is largely masked by a pervasive coating of Calcite micro-crystals as sub-mm colourless glassy rhombs which impart a light grey speckled film over the Siderite.  To one end, the Siderite is completely coated with drusy mounds of opaque creamy-white Calcite, built from sub-mm crystals.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780552958287,"sku":"CC12551","price":259.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC12551_732af651-9a7d-48cf-b267-4f30aa28ae98.jpg?v=1783969444","url":"https:\/\/crystalclassics.co.uk\/products\/siderite-with-calcite-1","provider":"Crystal Classics UK","version":"1.0","type":"link"}
