{"product_id":"siderite-5","title":"SIDERITE","description":"A wonderfully crystallised specimen of golden-tan Siderite from Knappenberg in Carinthia state, Austria. The habit of this excellent cabinet specimen is fractal-like in that each crystal, or group of crystals, is a subset of a similar, larger group, and repeated up to the largest. Individual, somewhat curved rhombic crystals of only a few millimetres group to form similar, slightly rotating offset larger structures which repeat up to the largest fan-like groups of over 3 cm across. All crystals have a satin to glassy lustre which, due to their curved surfaces and varying orientations form a patchwork of contrasting matt and reflective areas. A superb Knappenberg Siderite.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781012595023,"sku":"CC19044","price":370.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC19044_1037875b-7850-4514-86b3-73b9beab762e.jpg?v=1783975561","url":"https:\/\/crystalclassics.co.uk\/products\/siderite-5","provider":"Crystal Classics UK","version":"1.0","type":"link"}
