Black Obsidian is formed when molten lava cools rapidly without crystallisation creating a glassy, smooth texture. Black Obsidian is sometimes called the Stone of Truth. It can bring negative emotions and unpleasant truths rushing to the surface, which have to be confronted before peace can return. Black Obsidian is an extremely powerful and fast acting stone, and should be used with caution for Crystal Healing. Many people find Obsidian’s effects overwhelming and prefer to use a gentler stone.
Black Obsidian is a very protective stone. It is said to form a shield against negativity and to absorb negative energies from the environment. Because of this it should be cleansed regularly in running water. Place Black Obsidian on the Base Chakra for grounding.
In healing Obsidian is believed to reduce the pain of arthritis, to help joint problems and to ease cramp. It is also said to aid digestion.
