Libyan Desert Glass 5.07 g 19x19x12
Libyan Desert glass or Great Sand Sea glass is an impact glass, made mostly of Lechatelierite found in areas in the eastern Sahara / Libyan Desert in western Egypt.
These stones are shot on black to show color & detail, shooting on white washes out the photos.
The most famous would be a Scarab of LDG found with King Tut.
Over the past few years LDG supplies have dwindled, restricted access into the deep desert and export regulations have made obtaining new good stones hard.
