The Black Obsidian stone is primarily a grounding stone, making it a wonderful accompaniment of the root chakra, a.k.a the base chakra. The root chakra is located at the base of your spine, at your pelvic floor. It attaches you to grounding energy from the earth. 

A thoroughly balanced base chakra helps create a solid foundation for your life and provides stability to all other chakras above it. If your root chakra is unbalanced, you will experience instability in all areas of your life, and all remaining chakras will be unbalanced. 

Chakra imbalance causes physical illness as well as unbalanced energy flow. 

It combines the elements of fire, water, and earth.
