Physical properties

Hardness of 5.5 on the Mohs scale, black to dark brown color, vitreous luster, amorphous crystal structure, and a specific gravity of 2.3 to 2.5.

Formation & geological history

Formed by the immense heat and pressure of a meteorite impact melting terrestrial rocks, which was then splashed into the atmosphere and cooled rapidly.

Uses & applications

Primarily used as a collector specimen, in metaphysical practices, and occasionally cut into gemstones for unique jewelry.

Geological facts

Tektites often feature distinct, deep surface sculpturing called regmaglypts formed during atmospheric entry and cooling.

Field identification & locations

Identified by its amorphous glass-like texture, lack of internal crystal structure, and characteristic pitted or grooved surface; commonly found in strewn fields associated with major impact craters.
