Physical properties
Hardness 4-5 Mohs scale, dark brown to metallic gray color, metallic luster, octahedrite or hexahedrite crystal structure, specific gravity 7-8.
Formation & geological history
Formed in the early solar system approximately 4.5 billion years ago, originating from the core of differentiated asteroids before falling to Earth.
Uses & applications
Prized by collectors, scientific research, and occasional use in jewelry or custom knife-making.
Geological facts
Exhibits distinctive thumbprint-like depressions called regmaglypts formed by atmospheric ablation during entry.
Field identification & locations
Identify by extreme weight for size, magnetic attraction, and fusion crust; found globally in deserts and arid regions.
