Obsidian is believed to be a powerful protective and grounding stone, known for absorbing negative energy, promoting healing and facilitating personal growth.  Obsidian provides powerful spiritual protection, and acts as a mirror to confront and release negative energy, promoting grounding and balance by anchoring one to the earth and balancing chakras, facilitating mental and emotional healing by lessening stress, clarifying thoughts, and helping to release past traumas, and encouraging personal growth and self-discovery.
