Colombianite tektites are found in the departments of Antioquia and Caldas in Colombia. They are named after the country in which they were first discovered.

The type of rock that constitutes a Colombianite tektite is called quartz porphyry. This type of rock is made up of large crystals of quartz embedded in a smaller quantity of feldspar. The quartz crystals give the rock a glassy appearance, and the overall composition is similar to that of granite. There are two theories about how Colombianite tektites were formed. The first theory is that they were created when a large meteorite hit the Earth’s surface and vaporized the rocks in the area. The second theory is that they were formed by a volcanic eruption that hurled molten rock into the atmosphere, which then cooled and fell back to Earth as tektites. Due to that, Colombianite is also named “the lightning stone”.

Colombianite is a relatively rare tektite, with only a few hundred kilograms having been found. This makes it one of the most valuable and sought-after types of tektite by collectors.
