Formed by a massive impact near the Libyan border with Egypt, this impactite is one of the most sought after type. As a result of the heat and pressure of the impact event, desert sands were melted and formed an impact glass in a a wide range of shapes and colors from yellowish-white to yellow and black-yellow. They can have aerodynamic features similar to meteorites as a result of being thrown into the air in a molten state. Ancient Egyptians already knew about these rocks, and they picked them up and used them to make tools and jewelry for the Pharaohs, for example, for the famous Tutankhamun's pendant with Wadjet.
