{"product_id":"boulangerite-with-siderite","title":"BOULANGERITE   with SIDERITE","description":"Pale fudge coloured rhombic Siderite crystals protrude from a 'sea' of grey metallic fibres of Boulangerite. Boulangerite is rare in the mines in the Příbram District in the Czech Republic and when it does occur is is usually just a mat of grey metallic fibres infilling cavities or coating surfaces. This small cabinet specimen is unusual in having prominent well-formed Siderite crystals in association, making this a very distinctive piece. When one looks carefully at the display surface the detail is wonderful, dare I say attractive? Texturally, this is a lovely specimen and all the more remarkable to have no damage to either the Siderite crystals, or the Boulangerite which is impossible to clean when it gets dusty. Undoubtedly a historic Příbram specimen and one of significance.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781231321423,"sku":"CC30001","price":1110.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC30001_ea49efa5-ab0d-4ec3-b1ab-781419dd799c.jpg?v=1783983139","url":"https:\/\/crystalclassics.co.uk\/products\/boulangerite-with-siderite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
