{"product_id":"vog-siderite-italia-0","title":"SIDERITE – Rare Yellow Fan-Shaped Crystals, Brosso Mine, Italy","description":"\u003cp\u003eA striking specimen of Siderite from the historic Brosso Mine in Piedmont, featuring dense, fan-shaped lamellar crystal aggregates in an unusual and rare yellow coloration for the species. Most Brosso siderite develops a brown to reddish crust from surface iron oxide alteration, making this pale golden-yellow tone a genuinely distinctive find. The mine itself is now closed and largely inaccessible, adding to the appeal of well-formed specimens like this one for serious collectors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMineral Data:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 63 x 47 x 37 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 148 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProvenance:\u003c\/strong\u003e Brosso Mine, Calea, Lessolo, Metropolitan City of Turin, Piedmont, Italy\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ITALMINERAL","offers":[{"title":"Default Title","offer_id":45737752068205,"sku":null,"price":45.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8027\/6333\/files\/IMG20260724183844.jpg?v=1788068740","url":"https:\/\/www.italmineral.com\/products\/vog-siderite-italia-0","provider":"ITALMINERAL","version":"1.0","type":"link"}
