Black Obsidian is a stone of truth and transformation, forming a protective mirror that deflects negativity while anchoring you in strength. Like midnight glass, it cuts through illusion, revealing hidden patterns and supporting honest self-reflection. A trusted ally for shadow work and the Third Eye, it clears confusion, sharpens intuition, and shields from psychic intrusion. For Scorpios, it unveils buried fears, fortifies boundaries, and transforms pain into the courage of renewal.
