All Seeing Eye Engraved Black Obsidian plugs
With its glassy luster, obsidian is a distinctive stone. Obsidian is formed as lava from volcanic eruptions cools within the earth. The speed at which it cools prevents crystallization and the rock forms as solid volcanic glass.
Obsidian was revered by ancient cultures. It was one of the major barter materials, and prized for its ability to be worked to razor-sharp edges for arrows and spears. It has been used since prehistoric times for making tools, masks, weapons, mirrors and jewelry.
