Obsidian is technically not a crystal, but a volcanic glass, or an amorphous solid. It is formed with volcanic lava cools quickly. Other names are xaga or royal agate. With a hardness of 5-5.5, it contains no crystalline structure at all. Some obsidian has a gold sheen which is caused by gas bubbles in the lava. 

Black Obsidian is an extremely powerful protection stone and resonates with the root and third eye chakras the most. It cleanses and can seal the aura and helps create a kind of protective EMF shield for you. Obsidian is perfect for protection and cutting ties. As a spiritual cleanser, it absorbs psychic smog and helps you see more clearly. Having come directly from a volcano, obsidian contains the elements of earth water and fire making it a powerful tool both physically and spiritually.
