Black Obsidian is a powerful volcanic glass formed from rapidly cooling lava, renowned for its intense grounding and protective qualities. Often used as a "psychic vacuum cleaner," it is believed to absorb negative energy, stress, and emotional blockages from the environment and the wearer’s aura. Because of its mirror-like surface, it is frequently used in shadow work to reveal hidden truths and facilitate deep inner healing. By anchoring the spirit to the earth, Black Obsidian provides a sense of safety and clarity, making it a staple for anyone seeking to shield themselves from external negativity or emotional upheaval.
