Colombianites are transparent, gemmy, light smoky grey tektites exhibiting conchoidal surface, they are 5 million years old (Pliocene Epoch)
Colombianite is a sacred stone of the Colombian Indians from the Muisca tribes. The Indians call it “Piedra Rayo”, which means “Stone of Lightning” or “Light Stone”.
It is connected with the sacred, Divine origin. Colombian shamans use in their rituals as a means of communication with the god. They also use it for prophetic visions.
Created by the fall of a large meteorite approx. 5 million years ago. It is very rare, much rarer than Moldavite and in scientific circles, its origins were an enigma, now they are truly classed as Tektites.
