Authentic Muonionalusta Meteorite Cube – 339g Iron Nickel Space Specimen

This authentic Muonionalusta meteorite cube weighs an impressive 339 grams. Not only does the bold Widmanstätten pattern immediately stands out. But also the interlocking kamacite and taenite bands reveal themselves with striking clarity. Together, these features highlight the crystalline structure that formed as the meteorite cooled slowly in space over 4.5 billion years. Because of this rare process, each cube develops a metallic pattern that cannot be reproduced on Earth.

Moreover, this specimen comes from the Muonionalusta strewn field in northern Sweden. It offers a rare chance to own a scientifically significant piece of cosmic history. This meteorite originates from the core of an early planetesimal that broke apart in the asteroid belt. Its Widmanstätten pattern forms only through extremely slow cooling in space. This cube provides a tangible connection to the formation of our solar system and remains one of the most sought‑after meteorite types for collectors.
