Tektite is a unique type of natural glass formed during ancient meteorite strikes on Earth. It’s a high silica based stone that reminds one of small gravel pebbles, which can vary in size of a few centimeters (Tektites measuring in millimeters are called Microtektites). They’re normally found in various shades of black, but can also be seen as dark brown and grey (green shades of tektites found in Czech Republic are called Moldavite). Tektites can be found all over the world, with localities in the United States, China, Vietnam, Thailand, Australia, and throughout northwest Africa.
