This specimen is a fragment of the Muonionalusta iron meteorite, formed approximately 4.5 billion years ago and recovered from northern Sweden near the Muonio River.
Composed primarily of nickel-iron alloy, it is renowned for its well-defined Widmanstätten patterns, crystalline structures that became visible as the metal slowly cooled in space over millions of years.
The fragment shows natural fusion crust and weathering consistent with its long terrestrial residence, offering a detailed glimpse into the cooling history of its parent asteroid.
The picture shown is an example of the quality that you can expect to receive. Please be aware that, as these are natural products, they are subject to some variation.
