Lot 355
Libyan Desert Glass. 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 huge 830 gram 5 x 4.5 x 2 inch large specimen of Libyan Desert Glass is most unusual in having both white and green colorization but it also has a most unusual brownish-orange glass segment on one side. This probably resulted from a rare rock layer mixing with the desert sand at impact. This interesting specimen also possess the characteristic surface of small craters and voids that resulted from gasses escaping when the molten sand was solidifying in the atmosphere before being redeposited on the ground. This large almost 2 pound specimen of Libyan Desert Glass, found in the Sahara desert near the border between Libya and Egypt, is especially valuable as a small 125 gram specimen sold for over $6000 in a New York auction in October, 2007.
Add $15 for domestic shipping.
