Aletai 274.4 grams Specimen - Height: 9.1 cm - Width: 4.2 cm - 274.4 g

Extraordinary Aletai iron meteorite - 274.4 grams
Classification: Aletai ferrous meteorite (IVB)
Weight: 274.4 grams
Dimensions: 9.1 x 4.2 x 2.5 cm
Origin: Altai Mountains, Xinjiang region, China.
Treatment: antioxidant applied on the back.
Description:
Exceptional specimen of the Aletai iron meteorite with spectacular Widmanstätten figures perfectly visible on the polished and smooth surface. This magnificent sample displays the crystalline structures formed over millions of years of very slow cooling in space, a phenomenon impossible to replicate artificially on Earth.
The Aletai meteorite is one of the most important meteorite discoveries in China. The main mass was found in the Altai Mountains, in the Xinjiang region, and it represents one of the largest iron meteorites ever recovered in Asia.
Distinctive features
Magnificently well-defined Widmanstätten figures with interwoven geometric patterns.
Main surface completely polished to reveal the internal crystalline structure.
Partially preserved original fusion crust on the edges.
Professional antioxidant treatment on the back for optimal preservation.
Natural irregular shape that indicates a violent entry into the Earth's atmosphere.
Scientific and collecting importance
The Aletai iron meteorites belong to group IVB, extremely rare and mainly composed of an iron-nickel alloy with kamacite and taenite crystals. The Widmanstätten figures visible on this specimen are direct evidence of formation within the core of a planetesimal destroyed billions of years ago.
This is an exceptionally high-quality museum piece, perfect for serious collectors and scientific institutions. The combination of significant weight, spectacular crystal patterns, and documented provenance makes this specimen a truly rare acquisition opportunity.
Conditions: Excellent. Main surface professionally polished. Crystalline structure clearly visible. Conservation treatment applied.
An extraordinary piece of cosmic history that traveled through the solar system for billions of years before reaching Earth.
