Gibeon meteorites are composed of an iron-nickel alloy containing significant amounts of cobalt and phosphorus. The crystal structure of this meteorite provides a classic example of fine octahedrite and the Widmanstätten pattern is appreciated for its beauty both by collectors and designers of jewelry.

The fragments of the meteorite in the strewn field are dispersed over an elliptical area 390 kilometres (240 mi) long and 120 kilometres (75 mi) wide. The core of this area is situated near the village of Gibeon in Namibia’s Hardap Region. About 100–150 different fragments have been collected over time, and additional pieces are still found occasionally.
