These specimens occur in the copper-cobalt bearing sedimentary deposits of the Katanga Copperbelt, where barium-rich fluids precipitate barite in fractures or voids alongside Malachite, Chrysocolla, or Heterogenite; the bladed habit results from rapid crystallization in low-temperature hydrothermal environments, with crystals typically measuring several centimetres in length and showing occasional associations with secondary copper minerals that add green or blue accents.\u003c\/p\u003e\n\u003cp style=\"line-height: normal;\" class=\"MsoNormal\"\u003e\u003cb\u003ePRODUCT MINERALS \u003cbr\u003e\u003c\/b\u003eBarite\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"line-height: normal;\" class=\"MsoNormal\"\u003e\u003cb\u003ePRODUCT FEATURES \u003cbr\u003e\u003c\/b\u003eBladed\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"line-height: normal;\" class=\"MsoNormal\"\u003e\u003cb\u003ePRODUCT COLOUR \u003cbr\u003e\u003c\/b\u003eBlack, White\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"line-height: normal;\" class=\"MsoNormal\"\u003e\u003cb\u003eMOHS HARDNESS SCALE\u003ci\u003e\u003cbr\u003e\u003c\/i\u003e\u003c\/b\u003e3 to 3.5\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePRODUCT DATA \u003cbr\u003e\u003c\/strong\u003eLocality = Congo\u003cbr\u003eGrade = Very Good to A Grade\u003cbr\u003eSize = 20 - 41 mm \u003c\/p\u003e","brand":"BARITE","offers":[{"title":"Default Title","offer_id":50253115097281,"sku":"183-926-260522KW","price":2562.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2066\/6451\/files\/183926_4.jpg?v=1780247390","url":"https:\/\/www.toprocks.com\/products\/natural-rare-mini-bladed-barite-specimens-x-21-from-congo","provider":"Toprock Gemstones and Minerals ","version":"1.0","type":"link"}
