Introduction
Libyan Desert Glass: A Cosmic Gem Born from Catastrophe
Libyan Desert Glass is one of the most mysterious and fascinating natural materials found on Earth. This yellow-green glass is scattered across the Sahara desert near the border between Libya and Egypt. What makes it so captivating is not just its appearance but the story behind how it formed. Scientists believe it was created in an instant of intense heat, likely from a massive explosion caused by a space object entering Earth’s atmosphere. The idea is that either a comet or a meteor detonated above the desert, releasing enough energy to melt the sand beneath and fuse it into glass.
Our podcast highlights how this material is completely natural, not man-made, and can only form under extreme conditions. Some early theories suggested volcanic origin or lightning strikes, but neither could account for the scale or distribution of the glass. The current dominant theory is that a cosmic airburst, an explosion in the atmosphere without a direct impact, was powerful enough to vitrify the surface of the desert. This type of event is rare, but the evidence aligns with similar phenomena observed in modern times, such as the Tunguska explosion in Siberia in 1908.
One of the most remarkable facts presented in the video is that Libyan Desert Glass predates all human civilizations. It formed around 29 million years ago, long before humans existed. Yet it was still discovered and used by ancient cultures. The podcast points out that the glass was highly valued in ancient Egypt, with pieces found in royal tombs. Most famously, a carved scarab made from Libyan Desert Glass was placed in the pectoral ornament of King Tutankhamun. This connection between cosmic origin and royal symbolism adds a layer of historical depth to the glass, merging natural science with ancient belief.
We combine geology, astronomy, and archaeology to tell a story that feels almost mythical but is firmly rooted in scientific evidence. We explain the glass’s structure, its composition, and why scientists are certain it came from a high-energy atmospheric event. The glass is a permanent physical record of one of the most violent natural processes Earth can experience.

With over ten years of marketing experience, I finally decided to settle down in Bangkok to work in an area that I have always been interested in: the gemstones industry. I'm still learning how the market works on a daily basis, and I enjoy sharing my experience with those who are interested in learning more about gems in general.
