{"product_id":"siderite-twin-crystal","title":"SIDERITE (Twin Crystal)","description":"Twinned Siderite crystals are an absolute rarity on a world scale, with Mont Saint-Hilaire one of the few places where they are known. Even at Mont Saint-Hilaire they are rare, making this specimen something very special indeed - a masterpiece. At over 10 cm in length this beautifully coloured, zoned twin, is simply stunning. Even standard rhombic Siderite crystals from Mont Saint-Hilaire rarely exceed 5 cm in length, let alone a twin double that in size. What is more, this specimen is well-balanced, attractive, displays well, and has the contrast and association of a coating of white to cream Albite. It is likely that this specimen came out of the quarry during the 1970s or 1980s. A truly remarkable MSH specimen worthy of the finest collection.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781171224911,"sku":"CC25221","price":5551.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC25221_f78cf8cd-ba83-49f6-b894-710eebafd07c.jpg?v=1783980055","url":"https:\/\/crystalclassics.co.uk\/products\/siderite-twin-crystal","provider":"Crystal Classics UK","version":"1.0","type":"link"}
