Prehistoric�meteorite fragment from Namibia, longest edge approx. 45mm, set on card in ornate frame with damaged edges (plaster missing in several places), the frame 21 x 25cm. Estimated at over 4 billion years old. Card on reverse gives further information. Ex - Eric Dodd Auction, August 1999. This iron meteorite has in it a unique crystallization known as the Widmanst�tten crystal structure pattern, a result of cooling in outer space over billions of years. By far the largest known strewn field on Earth, the Gibeon meteorite field was first discovered by the Nama people of South Africa, who made use of the fragments as tools and weapons. Scientific study of the fragments began in 1836, after English captain J. E. Alexander sent samples to London.
