Colombianite is a term used to describe a particular type of tektite, which is a natural glass formed from terrestrial impacts of meteorites. Tektites are found in various parts of the world, and Colombianite specifically refers to tektites found in Colombia.
 
Tektites are formed when a large meteorite strikes the Earth's surface, creating intense heat and pressure. The energy from the impact melts the surrounding rock, ejecting it into the atmosphere. As this molten material cools and solidifies while falling back to the ground, it forms tektites.
 
Colombianite is known for its unique green color, which sets it apart from other tektites found in different regions. It has a glassy texture and is often shaped like a droplet or a button. Colombianite can be found in various sizes, ranging from small fragments to larger specimens.
