Likely iron meteorite fragment

Iron–nickel meteorite, probably kamacite with taenite; identification is uncertain from the photo alone

AI-generated identification · may be incorrect

Small, dark gray-brown, irregular and rounded, with a metallic-looking weathered surface. Iron meteorites are typically dense, metallic, Mohs 4–5, and have no visible cleavage; this specimen’s weight and a fresh cut or etched surface would help confirm it.

Physical properties

Small, dark gray-brown, irregular and rounded, with a metallic-looking weathered surface. Iron meteorites are typically dense, metallic, Mohs 4–5, and have no visible cleavage; this specimen’s weight and a fresh cut or etched surface would help confirm it.

Formation & geological history

If meteoritic, it is a fragment of a differentiated asteroid’s metallic core, formed billions of years ago and later delivered to Earth. Terrestrial iron-rich slag or a natural ironstone pebble can look similar.

Uses & applications

Confirmed iron meteorites are collected, displayed, and sometimes cut into jewelry or etched slices; they are not generally used as construction material.

Geological facts

An etched iron meteorite may show intersecting Widmanstätten patterns, but these cannot be seen on an unprepared surface.

Field identification & locations

Look for unusually high density, magnetic attraction, and a fusion crust; magnets alone do not prove it is a meteorite. Similar-looking terrestrial ironstone and industrial slag are common alternatives.
