{"product_id":"bultfonteinite","title":"BULTFONTEINITE","description":"Bultfonteinite is a rare fluorine-bearing hydrous calcium silicate which usually occurs as bunches of white acicular crystals, but specimens found at the N'Chwaning II mine are very different. This large miniature specimen shows this alternative form extremely well, comprising aggregates of somewhat spherical, finely crystallized pale pink Bultfonteinite upon dark grey manganese oxides. The spherules reach 2 to 3 mm in diameter and have a greasy lustre. The main crystallized aggregate is over 3.2 cm x 2.2 cm in extent, but many other smaller spherules and aggregates are present within cavities. This really is an excellent example of this species form, much larger than most specimens seen on the market, on matrix, and with no damage.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545386012847,"sku":"CC27159","price":2500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC27159.png?v=1770387771","url":"https:\/\/crystalclassics.com\/products\/bultfonteinite","provider":"Crystal Classics","version":"1.0","type":"link"}
