Likely iron meteorite fragment

Iron–nickel alloy, chiefly kamacite and taenite (Fe-Ni)

AI-generated identification · may be incorrect

Dark metallic-gray, silvery reflective surfaces, high density, and metallic luster; typically Mohs hardness about 4–5. The apparent worked-looking edge may be a fresh fracture or cut surface, and no crystal structure can be confirmed from the image.

Physical properties

Formation & geological history

Iron meteorites formed from the metallic cores of differentiated asteroids, most likely over 4.5 billion years ago, then survived atmospheric entry and weathering on Earth. Terrestrial slag, metallic rock, or industrial iron remain possible alternatives without testing.

Uses & applications

Meteorites are valued mainly by collectors and researchers; iron meteorites can be cut, polished, and etched to reveal Widmanstätten patterns. Estimated value is roughly $0.50–$5 per gram for common unclassified material, with authenticated specimens often $1,000–$10,000+ per kilogram.

Geological facts

A magnet should attract it strongly, and its unusually heavy feel is characteristic. A polished-and-etched slice showing interlocking Widmanstätten bands, plus nickel detection and professional classification, would confirm an iron meteorite.

Field identification & locations

Common terrestrial look-alikes include slag, hematite, magnetite, and machined steel. Check for fusion crust, regmaglypts, magnetic response, density near 7–8 g/cm³, and obtain laboratory nickel analysis before assigning meteorite value.
