piece of meteorite, 10-25 gr, cm 2.5-5.

The tektite is a type of natural glass chemically and structurally unique of meteoric origin, found on Earth in the vicinity of the equatorial regions around 80 ° latitude.
This species comes from alluvium in Thailand waste mining of rubies. There are two main theories about their origin:
A) glass meteor from the depths of space.
B) a type of impactite  produced in the craters formed by meteoric origin on the lunar or terrestial surface. Many of them are riddled, others are elongated due to the state liquefied.
Other places of discovery of the tektites are Australia, Vietnam and the Philippines.
