These 2cm Obsidian moon carvings are a dark and beautiful little piece — the deep black of Obsidian against the classic crescent moon form creates something both protective and mystical. Obsidian is a powerful volcanic glass and one of the strongest protective stones available, shielding against negative energy and psychic attack while grounding you firmly in the present. The moon shape connects this protective energy to the lunar cycle's themes of intuition, transformation, and the divine feminine. These are wonderful to carry, place on an altar, or add to a moon-themed crystal display.
