302 Gram chunk of Egyptian desert glass with semi-circle display
Egyptian or AKA Libyan Desert Glass is the remaining evidence of a tremendous asteroid or comet impact with the Earth. Some scientists think an air burst explosion caused the release of sufficient heat to melt and fuse the surface desert sand forming the desert glass.
This Desert Glass is found in the eastern Sahara Desert between the towering dunes of the Eastern Great Sand Sea of Egypt. Between these dunes are long narrow gaps where the bedrock is exposed. It is in these areas of exposed surface that this natural glass is found.
I've have heard that the Egyptian government has stopped the hunting and export of Libyan Desert Glass so it will not be available in the quantities it has been in the past.
Libyan Desert Glass is generally yellow in color but can also be very clear or even be milky or bubbly light yellow. Some fragments of this meteor glass have dark bands and swirls of brownish material. These dark areas are thought to be the melted cosmic body preserved in the meteor glass. Libyan Desert Glass was used in ancient times as a gem stone for the Pharaohs and remains a highly prized impact glass for collectors today.
You can search youtube for the documentary National Geographic has done on this amazing glass.
