{"product_id":"cronstedtite-on-siderite","title":"CRONSTEDTITE   on SIDERITE","description":"Cronstedtite is an extremely rare iron silicate species known in excellent crystals from just a small number of places. The most famous of those is Herja mine in Romania but very few larger display specimens survive the ravages of time, as most were collected over a century ago. This remarkable small cabinet specimen displays an absolutely magnificent dome-like aggregate of immaculate glossy black Cronstedtite crystals sat upon a crystallized Siderite matrix. A multitude of sparkling terminated crystal faces make up the 2.5 cm wide 'island' of Cronstedtite. The Siderite crystals are lenticular in form with a dark orange-brown external colour, but fudge coloured internally. There is no doubting that this is a world-class Cronstedtite worthy of the finest museum or private collection.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781218902351,"sku":"CC28783","price":7031.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC28783_37fe533b-28f7-4733-8293-0508d0c0b115.jpg?v=1783982516","url":"https:\/\/crystalclassics.co.uk\/products\/cronstedtite-on-siderite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
