Gibeon - Iron IVA

Gibeon is a classic IVA Iron meteorite from Namibia, first recognised scientifically in the 19th century after earlier use of the material by local peoples. It is one of the best-known Iron meteorites in the world and represents ancient iron-nickel material from the core of an early differentiated asteroid. Officially classified as Iron, IVA, Gibeon belongs to a well-studied chemical group and is widely recognised for its fine Octahedrite structure. The Meteoritical Bulletin records Gibeon from Namaland, Namibia, with numerous historic synonyms linked to its broad recovery area.

Gibeon specimens are especially valued for their fine Widmanstätten patterns, revealed when the metal is cut, polished, and etched. These interlocking crystal structures formed during extremely slow cooling in space over millions of years. Natural pieces may show weathered exterior texture from long terrestrial exposure, while prepared slices and etched sections display the elegant patterning that has made Gibeon popular for display, study, and jewelry. Its IVA classification and fine Octahedrite structure are key features of its identity.

Studying Gibeon provides insight into metallic core formation, slow crystallisation, and the evolution of early planetary bodies. Its long collecting history, Namibian provenance, stability, and attractive etched structure make it one of the most desirable Iron meteorites for collectors. Each specimen represents ancient asteroid core material, preserved in metallic form since the earliest history of the solar system.
