{"product_id":"cylindrite-with-toyohaite-and-potosiite","title":"CYLINDRITE with TOYOHAITE and POTOSIITE","description":"Rare pseudocubic crystals of metallic maroon Toyohaite (Ag2FeSn3S8) on botryoidal metallic micro-bladed crystals of Franckeite and Cylindrite from the Pirquitas silver-tin Deposit in Argentina.  Franckeite from this locality was once named Potos'ite, but this species has since been discredited and is now classified as a Sn(II)-poor (tin II) variety of Franckeite.  A nice example of some extremely rare minerals.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780938080591,"sku":"CC14736","price":111.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC14736_a3794321-580a-4a87-9bf0-90656ed2ee03.jpg?v=1783970941","url":"https:\/\/crystalclassics.co.uk\/products\/cylindrite-with-toyohaite-and-potosiite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
