Physical properties

Hardness of 4-5 on the Mohs scale, metallic gray color, metallic luster, cubic or octahedral crystal structure, high specific gravity (7.8-8.0).

Formation & geological history

Formed in the cores of differentiated planetesimals in the early solar system over 4.5 billion years ago, eventually falling to Earth.

Uses & applications

Valued by scientific researchers and private collectors for astronomical study, display, and occasionally custom jewelry.

Geological facts

Iron meteorites represent ancient planetary cores that were shattered by catastrophic impacts early in solar system history.

Field identification & locations

Identified in the field by extreme heaviness, magnetic properties, fusion crust, and characteristic Widmanstätten patterns when etched with acid. Found globally in designated strewn fields.
