{"product_id":"siderite-on-quartz-2","title":"SIDERITE on QUARTZ","description":"A superb, rich specimen of beautifully crystallised Siderite from Tincroft mine at Illogan, between Camborne and Redruth in Cornwall, England. Covering an elliptical matrix of massive milky-Quartz with a Hematite-rich core, the octahedral Siderite crystals range from 4 to 6 mm on edge and vary from semi-transparent golden-amber to a translucent dark chocolate-brown with hints of gold. The octahedral crystals, which are often chamfered along their edges with fine horizontal striations, have frosted prism faces making for a delightful example from the famous Tincroft mine. There is some minor contact damage on the highest protruding Siderite crystals, but still a wonderful classic Cornish specimen.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46543040479407,"sku":"CC12636","price":1000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC12636.png?v=1770304279","url":"https:\/\/crystalclassics.com\/products\/siderite-on-quartz-2","provider":"Crystal Classics","version":"1.0","type":"link"}
