Iron meteorite fragment (likely metallic meteorite)

Fe–Ni kamacite/taenite alloy; exact identification requires testing

AI-generated identification · may be incorrect

Small irregular gray-metallic fragment with a dull-to-slightly reflective luster; apparent hardness about 4–6, no visible cleavage, and likely high density. The image alone cannot distinguish meteorite metal from industrial slag or ordinary iron-bearing rock.

Physical properties

Small irregular gray-metallic fragment with a dull-to-slightly reflective luster; apparent hardness about 4–6, no visible cleavage, and likely high density. The image alone cannot distinguish meteorite metal from industrial slag or ordinary iron-bearing rock.

Formation & geological history

If genuine, it formed in a differentiated asteroid’s metallic core and crystallized billions of years ago, commonly 4.5 billion years old, before falling to Earth. Its rough shape may reflect atmospheric breakup or terrestrial weathering.

Uses & applications

Authentic meteorites are primarily collector and research specimens; iron meteorites may be cut, etched, and displayed. Value depends strongly on verified classification, mass, provenance, and aesthetics.

Geological facts

A magnet attraction, unusually high density, and a fused dark crust can support identification, but are not conclusive. Many suspected meteorites are slag, rusted industrial metal, or furnace byproducts.

Field identification & locations

Check for strong magnetism, density, a thin fusion crust, and absence of abundant bubbles; avoid grinding until tested. Professional analysis using nickel content and microscopy is required; common finds occur in deserts and Antarctica.
