The Rustenburg area of South Africa's North West Province sits within ancient Precambrian geology and has long been a source of quality decorative stone, producing Green Marble with attractive natural veining and a consistent depth of colour suited to lapidary and display work. The interlocking Calcite crystal structure of the rock accepts a high polish, bringing out the full richness of the green tones and the contrast of any white or grey veining present. South African Green Marble is an underrated decorative stone with excellent visual appeal and good structural integrity.\u003c\/p\u003e\n\u003cp style=\"line-height: normal;\" class=\"MsoNormal\"\u003e\u003cb\u003eASSOCIATED MINERALS \u003cbr\u003e\u003c\/b\u003eCalcite, Chlorite, Serpentine, Dolomite\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"line-height: normal;\" class=\"MsoNormal\"\u003e\u003cb\u003eASSOCIATED FEATURES \u003cbr\u003e\u003c\/b\u003eTrigonal, Granoblastic, Vitreous, Recrystallised\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"line-height: normal;\" class=\"MsoNormal\"\u003e\u003cb\u003eASSOCIATED COLOURS \u003cbr\u003e\u003c\/b\u003eGreen, White, Grey, Cream\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\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003ePRODUCT DATA \u003cbr\u003e\u003c\/b\u003eLocality = Rustenberg, South Africa\u003cbr\u003eGrade = Good Grade\u003cspan style=\"mso-spacerun: yes;\"\u003e                      \u003c\/span\u003e\u003cbr\u003eSize = 99 - 110 mm\u003c\/p\u003e","brand":"MARBLE - Green","offers":[{"title":"Default Title","offer_id":50485502247105,"sku":"187-132-260811BM","price":2716.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2066\/6451\/files\/187132_5.jpg?v=1786459559","url":"https:\/\/www.toprocks.com\/products\/polished-green-marble-sphere-x-2-from-rustenberg-south-africa","provider":"Toprock Gemstones and Minerals ","version":"1.0","type":"link"}
