Natural Libyan Desert Glass tektite specimen, 439.0 carats

Libyan Desert Glass is a natural glass formed approximately 29 million years ago from a meteorite impact or airburst in the Sahara Desert between Libya and Egypt. This rare tektite material was created when intense heat from the impact melted the desert sand, creating these distinctive yellowish-green glass formations. The glass has been prized since ancient times, with specimens found in King Tutankhamun's tomb, demonstrating its historical significance. Libyan Desert Glass is highly sought after by meteorite collectors, mineral enthusiasts, and those interested in impact geology. The material's rarity, extraterrestrial origin, and connection to ancient Egyptian culture make it particularly valuable to collectors of natural history specimens and tektites. Its unique formation story and limited geographic source add to its appeal among serious collectors who appreciate both its scientific importance and aesthetic qualities.
