These unusual jet black tektites are from mainland China. Natural specimens from Maoming City, Guang Dong,
Province, China generally show more unusual shapes with much deeper pitting and furrowing than other tektites.
Since no one has ever seen a tektite being made their true origin is not yet known it is believed that they were formed
approximately 15 million years ago when a huge meteorite collided with the earth with such force that melted rock
and meteoritic fragments are thrown at high speeds into the upper atmosphere. Here they cool and harden, preserving
their splashed, melted shape, later they rained down on China. Tektites are found in areas that often our thousands of miles apart.
