Tektites due to being a product of extra terrestrial phenomena, are associated with worlds outside our own. 
They are believed to facilitate communication with otherworldly realms and encourage spiritual growth.
Most of these stones are considered mystical since ancient times and used for psychic protection against negative entities and influences. 
A Tektite is a rare natural glass formed when an asteroid strikes the Earth.
Tektites can be found at least five widely separated locations on the Earth.
