Physical properties
Hardness: 6-7 (Mohs scale), Color: Jet black to dark brownish-black, Luster: Vitreous (glassy), Structure: Amorphous (non-crystalline), Cleavage: None (conchoidal fracture), Specific Gravity: 2.3-2.5
Formation & geological history
Formed from terrestrial debris ejected during a meteorite impact that undergoes rapid melting and cooling while traveling through the atmosphere. This specimen likely belongs to the Australasian strewn field, approximately 790,000 years old.
Uses & applications
Predominantly used as a collector specimen, in jewelry making (faceted or raw), and within metaphysical practices.
Geological facts
Tektites are not meteorites themselves; they are the terrestrial 'splash' created when a meteorite hits Earth. The name comes from the Greek word 'tektos' meaning molten.
Field identification & locations
Identify by its pitted or 'pockmarked' surface (lechatelierite inclusions), glassy interior when chipped, and lack of magnetism. Commonly found in 'strewn fields' such as those across Southeast Asia, Australia, and parts of Europe.
