Obsidian

Black Obsidian is a very powerful grounding stone, allowing for one to feel totally of the earth whatever the environment. This crystal is recommended for grounding during astral travel or anytime that extra grounding is needed. Black Obsidian also protects against psychic attack, shielding negative energies and emotions from yourself. This is a stone-point arrow head made from natural black obsidian. This piece is good for grounding, protection, and spiritual communication.
