The Rustenburg area of South Africa's North West Province sits within ancient Precambrian geology and produces a clean, fine-grained white Marble with excellent structural integrity suited to lapidary work. These spheres have been cut and polished to a smooth high lustre finish, revealing the subtle crystalline texture and occasional veining characteristic of the Rustenburg material. White Marble has been prized for centuries for its purity of colour and the quality of polish it accepts.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eASSOCIATED MINERALS \u003cbr\u003e\u003c\/b\u003eCalcite, Dolomite\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eASSOCIATED FEATURES \u003cbr\u003e\u003c\/b\u003eTrigonal, Granoblastic, Vitreous, Recrystallised\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eASSOCIATED COLOURS \u003cbr\u003e\u003c\/b\u003eWhite, Cream, Grey\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"line-height: normal;\"\u003e\u003cb\u003eMOHS HARDNESS SCALE\u003ci\u003e\u003cbr\u003e\u003c\/i\u003e\u003c\/b\u003e3\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003ePRODUCT DATA \u003cbr\u003e\u003c\/b\u003eLocality =  Rustenburg, South Africa\u003cbr\u003eGrade = Very Good Grade\u003cspan style=\"mso-spacerun: yes;\"\u003e                      \u003c\/span\u003e\u003cbr\u003eSize = 228 mm\u003c\/p\u003e","brand":"MARBLE - White","offers":[{"title":"Default Title","offer_id":50405960286401,"sku":"186-159-260714BM","price":12544.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2066\/6451\/files\/186159_4.jpg?v=1784268630","url":"https:\/\/www.toprocks.com\/products\/polished-xl-white-marble-sphere-x-1-from-rustenburg-south-africa","provider":"Toprock Gemstones and Minerals ","version":"1.0","type":"link"}
