Physical properties
Hardness: 5.5-6.5; Color: Jet black to brownish-black; Luster: Vitreous to dull; Crystal structure: Amorphous (non-crystalline glass); Specific gravity: 2.3-2.5
Formation & geological history
Formed roughly 788,000 years ago during a massive meteorite impact in Indochina. The impact ejected terrestrial silica-rich debris into the atmosphere, which melted and solidified into glass as it fell back to Earth.
Uses & applications
Popular for mineral collection, metaphysical jewelry (spiritual protection), and scientific research into impact events.
Geological facts
Tektites contain almost no water, making them much drier than any volcanic glass found on Earth. Indochinites are part of the largest known strewn field on the planet.
Field identification & locations
Identify by its pitted, sculpted surface (aerodynamic ablation) and its distinct black color. Found primarily in Southeast Asia, Australia, and parts of China.
