Choose an individually photographed Muonionalusta Meteorite Slice, professionally cut, polished and etched to reveal its distinctive Widmanstätten pattern.
Muonionalusta is officially classified as an Iron, IVA meteorite and was first documented in Sweden in 1906. Each prepared slice displays a unique arrangement of interlocking iron-nickel crystals, revealed through careful polishing and etching.
The Widmanstätten pattern developed as iron-nickel metal cooled extremely slowly within its parent asteroid. Its geometric bands are formed by the intergrowth of the iron-nickel minerals kamacite and taenite under conditions found within asteroid interiors.
Every slice has been individually catalogued and photographed, allowing you to select the exact specimen you will receive. Differences in outline, pattern, inclusions and surface characteristics make every piece unique.
Why This Specimen Is Special
The appeal of these specimens lies in their clearly visible Widmanstätten patterns. Professional preparation reveals the internal crystalline structure of the meteorite, transforming each slice into an individual record of slow cooling within an ancient asteroid.

Specimen Preparation
Each Muonionalusta slice has been:
- Professionally cut
- Carefully polished
- Etched to reveal the Widmanstätten pattern
- Individually photographed
- Assigned a GeoFossils specimen number
Etching exposes the contrasting kamacite and taenite structures within the iron-nickel metal. The pattern and inclusions differ naturally across each slice.
