THE MINERAL OBSIDIAN
Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a "mineraloid." The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture. Black is the most common color of obsidian. However, it can also be brown, tan, or green. Rarely, obsidian can be blue, red, orange or yellow. The colors are thought to be caused mainly by trace elements or inclusions. Black Obsidian Stone is a powerful cleanser of psychic smog created within your aura, and is a strong psychic protection stone. It has powerful metaphysical properties that will shield you against negativity, and the energy of these stones may stimulate the gift of prophecy.
