Libyan desert glass is a substance found in areas in the Libyan Desert. The origin of the glass is a controversial issue for the scientific community, w/many theories. Meteoritic origins for the glass were long suspected, and recent research linked the glass to impact features, such as zircon-breakdown, vaporized quartz and meteoritic metals, and to an impact crater. Libyan desert glass has been dated as having formed about 26 million years ago. Offered here is a 1.25x2x1.5" tall superb specimen of chartreuse-colored Libyan desert glass that weighs 47 grams and was found in the sands of the Libyan Desert near the Gilf Kebir Plateau in Egypt. The specimen's exterior is pock-marked w/numerous scoops that have been smoothed, the result of countless years of sandblasting by desert winds. Libyan desert glass was revered by the Ancient Egyptian civilization and found in the tomb of the Pharaoh Tutankhamun. Rarely is Libyan Desert Glass as translucent and as beautiful as the specimen offered here, which shows only a few inclusions of foreign matter within. Wonderful to display. From the Robert M. Overstreet Collection and comes with COA.
