Genuine Indochinite Tektites

Tektites are glassy objects associated with meteoric impacts. Their hardness ranges from 5-5 to 6.5, and their crystal system is amorphous. Tektites are rich in silica, with silicon dioxide content ranging from 68% to 82%. The name Tektite comes from 8the Greek word tektos, meaning molten. The classic forms of Tektites-teardrops, smooth rounded
"buttons and dumbbells suggest that these stones were, at the time of the associated meteoric impact, heated to the liquid state and flung through the atmosphere. Scientists have long debated whether Tektites were themselves meteorites, terrestrial rocks melted by meteoric impacts, or some fusion of terrestrial and extraterrestrial material. Most Tektites are black or brown-black, with bottle-green Moldavite a notable exception. Tektites have been found in North America, Australia, Africa, China and Southeast Asia. The most abundant Tektites are those found in the vast strewn fields that encompass China and Indochina.
