Obsidian is a grounding stone. It helps with growth and energizes fortitude and aids one in overcoming difficult situations. Black Obsidian exposes truth so that challenges and disharmonious circumstances are able to confronted and overcome. Placing one under your pillow may have a calming effect but it can also, temporarily, produce anxiety as obstacles are brought to the forefront for resolution.
Perfect for holding tightly at approximately 1" x1.5" (30 x 45mm).
