{"product_id":"siderite-pseudomorph-after-calcite-with-quartz","title":"SIDERITE Pseudomorph After CALCITE with QUARTZ","description":"An excellent epimorphic, light caramel Siderite replacement of intergrown rhombic Calcite crystals from Turț at Negrești-Oaș in the Oaș Mountains of Satu Mare County, Romania.  Crystalline Siderite forms excellent, well-defined rhombic epimorphs, some with egg shell-thin walls infilled with drusy undulating granular Siderite together with the odd Quartz crystal.  This complex mixture of epimorphs and sucrosic crystallised Siderite covers a 9 x 5 cm area of underlying Pyrite.  An unusual cabinet specimen and fine example of complex epimorph replacement chemistry.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780513636687,"sku":"CC12023","price":296.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC12023.png?v=1779742089","url":"https:\/\/crystalclassics.co.uk\/products\/siderite-pseudomorph-after-calcite-with-quartz","provider":"Crystal Classics UK","version":"1.0","type":"link"}
