Found in alkali pegmatites of the Chilwa Alkaline Province, these crystals often grow in complex clusters or as single specimens, frequently associated with Orthoclase, Smoky Quartz, and Zircon. Zomba Aegirine is notable for its lustrous, vitreous sheen and monoclinic crystal structure. Some crystals display unique pyramidal terminations or partial alteration to Riebeckite, adding to their geological intrigue. These specimens, often set against light-colored feldspar, are visually captivating and highly valued by collectors for their aesthetic and scientific significance.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003eASSOCIATED MINERALS \u003cbr\u003e\u003c\/b\u003eAegirine, Orthoclase, Feldspar, Smokey Quartz, Zircon, Arfvedsonite\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eASSOCIATED FEATURES\u003c\/strong\u003e \u003cbr\u003eTerminated, Elongated, Prismatic, Needle, Matrix, Oily Luster, \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eASSOCIATED COLOURS\u003c\/strong\u003e\u003cbr\u003eBlack, Green, Smokey, White\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMOHS HARDNESS SCALE\u003ci\u003e\u003cbr\u003e\u003c\/i\u003e\u003c\/b\u003e\u003ci\u003e5-6\u003c\/i\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePRODUCT DATA \u003cbr\u003e\u003c\/strong\u003eLocality = Zomba, Malawi\u003cbr\u003eGrade = Good to A Grade\u003cbr\u003eSize = 29 - 57 mm \u003cbr\u003e\u003c\/p\u003e","brand":"AEGIRINE","offers":[{"title":"Default Title","offer_id":50762238263489,"sku":"189-588-261016BM","price":2072.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2066\/6451\/files\/189588_5.jpg?v=1792507268","url":"https:\/\/www.toprocks.com\/products\/natural-aegirine-bag-of-1-28-kg-lot-single-crystals-from-zomba-malawi","provider":"Toprock Gemstones and Minerals ","version":"1.0","type":"link"}
