BLACK OBSIDIAN is a protective stone, often worn to guard against negativity, demanding people, hostile entities and geopathic stress. Obsidian protects the wearer from hostility, negativity, psychic �vampires� and spiritual entities that do not belong.
It is helpful in developing intuition and grounding you to the earth, releasing negative energies.
Physically, Obsidian often points to the root cause of an illness. It clears the blockages that cause disease.
