{"product_id":"sphalerite-with-siderite","title":"SPHALERITE with SIDERITE","description":"A choice, tightly packed group of metallic black Sphalerite crystals to 2.3 cm cover a deep buff to creamy-tan matrix of small saddle-habit Siderite crystals. From the mining area around Nenthead on Alston Moor in east Cumbria, the Sphalerite crystals are typically squat with complex growth structures on each face and have a silky lustre.   Although the specimen is labelled as Siderite, this is likely to be Ankerite.  A good cabinet display specimen.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584047960239,"sku":"CC13626","price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC13626.png?v=1771841656","url":"https:\/\/crystalclassics.com\/products\/sphalerite-with-siderite","provider":"Crystal Classics","version":"1.0","type":"link"}
