It is classified as a Fine Octahedrite and represents iron-nickel material from the core of an ancient differentiated asteroid. After forming over 4.5 billion years ago, the parent body cooled extremely slowly in space before being disrupted, with Muonionalusta eventually reaching Earth and later being preserved in glacial deposits. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"550\" data-end=\"1132\"\u003ePrepared Muonionalusta specimens are especially recognised for their fine Widmanstätten patterns, revealed when the metal is cut, polished, and etched. These interlocking crystalline structures formed during exceptionally slow cooling and are one of the key visual features of IVA Iron meteorites. Natural exterior pieces may show weathered surfaces from long terrestrial exposure in an Arctic environment, while slices and etched pieces display the internal pattern that has made Muonionalusta one of the most widely collected Iron meteorites. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1134\" data-end=\"1589\"\u003eFor collectors, Muonionalusta offers a strong combination of recognised classification, attractive patterning, and historic Scandinavian provenance. Its availability in a range of specimen types makes it suitable for display, study, or jewelry use, while its age and structure provide a direct connection to early asteroid core formation. Each specimen is a genuine piece of ancient space metal from one of the most familiar and desirable Iron meteorites.\u003c\/p\u003e","brand":"OuterSpacer Meteorites","offers":[{"title":"Default Title","offer_id":56654347239750,"sku":"MMS-06\/16","price":27.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/0518\/8678\/files\/s-l1600_834acfb3-10d7-4f54-b45c-b689878fc850.jpg?v=1794307066","url":"https:\/\/outerspacer.com\/products\/muonionalusta-iron-iva-polished-etched-offcut-7-18g-sweden","provider":"OuterSpacer Meteorites","version":"1.0","type":"link"}
