{"product_id":"ettringite-3","title":"ETTRINGITE","description":"Excellent short and long prismatic hexagonal terminated crystals of bright, acidic lemon-yellow Ettringite are beautifully scattered across a pale-grey druse of sparkling micro-crystals of Quartz with Hematite inclusions. This gorgeous specimen is from the world-famous N'Chwaning mines at Kuruman, in the Kalahari Manganese Field of South Africa. Three mines work this hydrothermally sediment-enriched orebody, the N'Chwaning I, II and III mines, but specimens cannot often be attributed to a specific mine, hence the collective mine name. The Ettringite crystals attain around 9 x 8 x 6 mm and are all perfectly euhedral and undamaged, forming as doubly-terminated hexagonal prisms with pointed pyramidal hexagonal terminations. When the prism is short, the crystals are lenticular and when a little longer, become a stubby barrel-shape and all with a glassy lustre. This is a extremely fine Ettringite specimen from the N'Chwaning mines, whose crystals contrast wonderfully against the Quartz matrix.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780459995471,"sku":"CC11101","price":2591.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC11101_137c4a0c-534a-4c9f-841c-f1d78b632e37.jpg?v=1783968426","url":"https:\/\/crystalclassics.co.uk\/products\/ettringite-3","provider":"Crystal Classics UK","version":"1.0","type":"link"}
