Etched GIBEON Meteorite 12 grams, Octahedral Form

This is a Gibeon meteorite specimen that was being fashioned into a cylinder shape--it was cut, smoothed, and etched with Nitric acid to reveal the crystalline pattern known as the Widmanstätten Pattern--resulting from the octahedral crystalline structure from the meteorite cooling very slowly over millions of years. Apparently the cylinder cracked along a weakened plane. The exposed interior shows the octahedral crystal makeup of this iron meteorite. And the smoothed and etched exterior shows the Widmanstätten pattern.

The Gibeon meteorite fell approximately 12,000 years ago in Namibia , Africa . It is a Classified Iron Octahedrite (IVA).

This specimen measures 3.1 cm by 1.5 cm by 1 cm thick. It weighs 12 grams.
