Caption

This Iron (III E) Meteorite contains a distinctive crystal pattern known as the Widmanstaten structure. It was fashioned over thousands or millions of years in a low gravity environment at an extremely low rate of cooling producing large crystals of nickel-rich and nickel-poor metallic bands. Such a structure is impossible to forge making the identity of this and similar iron meteorites absolute. Laboratories are only able to imitate it on the microscopic scale. This sample has been cut, polished and etched with acid to enhance the view of the Widmanstaten structure.
