One large pocket was found 7 or 8 years ago from the Ambositra\/Ivato area in Central Madagascar,  but we have seen very little to none since then.  This sometimes displays shades of blue  (Bornite content) pink, purple (Covelline), black, and an iridescent patina. The patina varies in both quantity and quality, with some specimens showing partial coatings that reveal stunning white crystals, ranging from small to medium-sized, intricately arranged in dense formations. This remarkable material is a coveted find for collectors, offering a singular addition to any collection. Pricing is based on grade, not by weight. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eASSOCIATED MINERALS\u003c\/strong\u003e\u003cbr\u003eGoethite, Quartz, Hematite\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eASSOCIATED FEATURES\u003c\/strong\u003e \u003cbr\u003eIridescent\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eASSOCIATED COLOURS\u003c\/strong\u003e\u003cbr\u003eMulti Coloured\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePRODUCT DATA \u003cbr\u003e\u003c\/strong\u003eLocality = Ambositra, Madagascar\u003cbr\u003eGrade = Good Grade\u003cbr\u003eSize = 122 - 146 mm \u003cbr\u003e\u003c\/p\u003e","brand":"QUARTZ - Blacknite","offers":[{"title":"Default Title","offer_id":50658102640833,"sku":"188-960-260928BM","price":2352.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2066\/6451\/files\/188960_9.jpg?v=1790861433","url":"https:\/\/www.toprocks.com\/products\/natural-large-goethite-coated-blacknite-quartz-crystals-x-2-from-madagascar","provider":"Toprock Gemstones and Minerals ","version":"1.0","type":"link"}
