Libyan Desert Glass
Libyan desert glass is a rare natural material found in the Great Sand Sea region, on the border of Egypt and Libya. This type of glass has a very high silica content (up to 98%) and is considered one of the purest forms of natural glass in the world. Its color ranges from transparent yellow to bright greenish-yellow shades.
Origin
Libyan desert glass formed approximately 26–29 million years ago, although its exact origin is still debated among scientists. The most common theory suggests that this glass was formed by extreme temperatures during a meteorite impact, which caused melting and solidification of surface rocks. Another hypothesis suggests an atmospheric explosion (an “airburst”) that generated enough heat without leaving an impact crater.
Historical and Cultural Significance
Libyan desert glass was already known in ancient Egypt. One of the most famous artifacts made from this glass is a scarab set in the necklace of Pharaoh Tutankhamun. This necklace was found in his tomb and is considered one of the most valuable artifacts from ancient Egypt.
Use
Jewelry: Thanks to its unique color and purity, Libyan desert glass is popular among jewelers. It is used to make necklaces, rings, pendants, and other decorative items. Due to its mysterious origin and unusual appearance, it has high aesthetic value, making it an attractive material for jewelry.
Collectibles: Mineral and tektite collectors highly value Libyan desert glass. Its rarity and connection to ancient history, such as the artifacts from Tutankhamun’s tomb, make it a highly prized collectible.
Scientific Use: Libyan desert glass also has significant scientific value. Geologists and planetary scientists study it to understand impact processes and high-temperature events caused by meteorite impacts.
