-17 cm!!!- Amazing XL Muonionalusta METEORITE Slice (Sweden, 1906) Widmanstätten Pattern. - 125.5 g

The Muonionalusta meteorite is one of the oldest known iron meteorites, discovered in Sweden and dating back to about 1906. Slices of this meteorite are prized for displaying the Widmanstätten pattern, a distinctive interlocking crystalline structure of iron and nickel alloys that forms very slowly as the metallic core cools in asteroids over millions of years. This pattern is not replicable under earthly conditions, making meteorites like Muonionalusta scientifically valuable and visually striking. The exceptionally large and well-preserved slices allow collectors to appreciate the natural metallic art and offer insights into the cooling history of planetary cores. Such specimens are not only jewel-like in appearance but also serve as important tools for studying planetary differentiation and asteroidal metallurgical processes.
