Muonionalusta - Iron, IVA - Polished & Etched Offcut - 7.18g - Sweden

A 7.18g offcut of Muonionalusta, polished, etched and sealed to show the Widmanstätten pattern of this IVA iron from northern Sweden.

Muonionalusta is a well-known IVA Iron meteorite from northern Sweden, first discovered in 1906 near the village of Kitkiöjärvi in Norrbotten County. 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.

Prepared 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.

For 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.
