Since not everything about how this natural glass forms is fully understood adding to the charm and mystery of this rare material, and for clarification a Tech tight is not a meteorite, however it is often referred to as meteorite material because it only forms from the debris caused by the impact from one..........................Libyan Desert Glass is the remaining evidence of a tremendous asteroid or comet impact with the Earth. Some scientists think an air burst explosion caused the release of sufficient Heat to melt and fuse the surface desert sand forming the Libyan Desert Glass. It's only found in the Eastern Sahara Desert between the Towering Dunes of the Egyptian Great Sand Sea of Egypt. Between these Dunes are long narrow gaps where the Bedrock is exposed. It is in these areas of exposed surface that this natural glass is found. Libyan Desert Tektites are generally yellow in color but can also be very clear or milky, and there may be bubbles present as well as areas that are lighter or darker than the rest of the material. Some fragments of this meteor glass have dark bands and or swirls of brownish material. These dark areas are thought to be the melted Cosmic body preserved in the meteor glass. Most notably, it was used in ancient times as a gemstone for the Pharaohs and remains a highly prized impact glass for collectors today. It is now known publicly that the Egyptian government has stopped the hunting and export of Libyan Desert glass, so we can expect to see the supply that may be available now, mainly on the online Market start to dry up as it is currently one of the most popular Tektites and the second most popular, just after Moldavite which is the most popular & well-known Tektite ProductExpirationType : Does Not Expire ProductSiteLaunchDate : 2023-02-27T08:00:00.000Z Size : 2.75 - 4.25 Gram SupplierDeclaredDgHzRegulation : not_applicable UnitCount : 1
