Large Libyan Desert Glass Tektite. Tektites are a mixture of earth rocks mixed with a sprinkling of meteorite material from an immense explosive event that occurred when a very large rocky meteorite vaporized before impacting the earth. The resulting mixture forms glass-like mixture. The color is usually black but it can also be green or yellow depending on the amount of silica present. This large 3 ½ X 3 inch 307 gram specimen of Libyan Desert Glass from a meteorite impact 29 million years ago is unusually pristine from being buried in the sand in the Sahara desert (near the border of Libya and Egypt) It is a yellow to medium green in color with about 20 % of its top being a smooth glossy light green from being sand blasted on the surface and the remainder buried in the sand having the original lightly pitted surface along with some holes that resemble regmaglypts. Most specimens of Libyan desert glass are a pale yellow color unlike the deeper more vibrant yellow-green color of this superior specimen. Estimated Value $500 - 900
