LIBYAN DESERT GLASS

This is a natural untreated specimen of Libyan desert glass in its natural form as found in the desert.

Between the towering dunes of the Eastern Great Sand Sea of Egypt are long narrow gaps where bedrock is exposed. It is in these areas of exposed surface that a wondrous natural glass is found. Libyan Desert Glass is the remaining evidence of a tremendous asteroid or comet impact with Earth. Probably an air burst explosion caused the released sufficient heat to melt and fuse to glass the surface of the ground. Libyan Desert Glass is generally yellow in color. It can be very clear or it can be a milky, even bubbly light yellow. Some fragments have dark bands and swirls of brownish material. It is in these dark areas that some of the melted cosmic body is believed by some to be preserved. Libyan Desert Glass was used in ancient times as a gem stone for the Pharaohs and remains a highly prized impact glass for collectors today.it is said cleopatra like to wear this stone in her jewelery.

The origin of the glass is a controversial issue for the scientific community, with many evolving theories. Meteoritic origins for the glass were long suspected, and recent research linked the glass to impact mechanics, such as vaporized quartz and meteoritic metals, and to an impact crater. Some geologists associate the glass not with impact melt ejecta, but with radiative melting from meteoric large aerial bursts. If that were the case, the glass would be analogous to trinitite, which is created from sand exposed to the thermal radiation of a nuclear explosion. The Libyan desert glass has been dated as having formed about 26 million years ago. It was knapped and used as a tool during the Pleistocene Era.

Why are users outbidding themselves?

When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.

When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.

Audit

The Gemstone Sheriff program allows our members to request an audit on any product, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
