Colombianite, also known as Piedra Rayo, is an ancient form of Obsidian black glass and tektite. It was estimated that these stones are around 30 million years old, which is extremely unique for any type of Obsidian. Most Colombianite forms in small. Upon first glance, you may think that this is a solid stone that is unable to be penetrated by light. However, shining a light through Colombianite will result with a smoky or yellow transparent color that shines through.
