This is a very nice, and highly translucent specimen of Libyan Desert Glass. And if you don't know what that is, well then, get ready to be amazed!
Look below for large photos!
This is what was formed from an ancient meteorite impact in the middle of the deserts of Egypt. The sand was immediately fused into this beautiful yellow glass!
It is highly collectible and more and more rare all the time. It it getting more difficult to find and I was just selling some stuff that I had in an old collection.
So I am offering this beautiful piece for you. Times are tough and I am just trying to make some money, and I know it will find a nice home out there somewhere. This specimen weighs 12.54 carats which is 2.78 grams, and is 22 mm long by 18 mm wide by 8 mm thick.
It is really really beautiful, and it what a great present or just to buy for yourself. If you have any questions, do not hesitate to ask me.
Have fun bidding, and know that I will ship this out the same day as the payment clears. Thanks so much for visiting my auction and have a great day:>)

The origin of the glass is a controversial issue for the scientific community, with many evolving theories. Meteoric origins for the glass were long suspected, but recent research linked the glass to impact mechanics, such as vaporized quartz and meteoric 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 fireball .

Tektites (from Greek tektos , molten) are natural glass rocks up to a few centimeters in size, which most scientists argue were formed by the impact of large meteorites on Earth 's surface. Tektites are typically black or olive-green, and their shape varies from rounded to irregular.

Tektites are among the "driest" rocks, with an average water content of 0.005%. This is very unusual, as most if not all of the craters where tektites may have formed were underwater before impact. Also, partially melted zircons have been discovered inside a handful of tektites. This, along with the water content, suggests that the tektites were formed under phenomenal temperature and pressure not normally found on the surface of the Earth.

The terrestrial-impact theory states that a meteorite impact melts material from the Earth's surface and catapults it up to several hundred kilometers away from the impact site. The molten material cools and solidifies to glass. According to this theory, a meteorite impact causes their formation, but the precursor material of tektites is primarily of terrestrial origin, as de...
