{"product_id":"nifontovite","title":"NIFONTOVITE","description":"This excellent crystallised miniature is a fine example of the extremely rare borate, Nifontovite, from Charcas in San Luis Potos', Mexico.  This polymetallic skarn deposit is defined by an extensive calcium-boron metasomatic envelope and contains over twenty quite varied mineral species.  The Nifontovite crystals measure up to 2.7 cm long and are colourless with a brilliant glassy lustre.  The crystals form a compact group giving an overall slightly milky appearance.  Most crystals are sharply terminated and protrude from a micro-vuggy, cream coloured Calcite matrix.  The back face of the matrix is pervaded with a spray of embedded Nifontovite crystals which make a fine addition to this rare specimen.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781208383823,"sku":"CC28163","price":925.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC28163_d271c839-2010-4e15-a830-77e2674c0004.jpg?v=1783981781","url":"https:\/\/crystalclassics.co.uk\/products\/nifontovite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
