Black Obsidian is one of the most protective stones available, being particularly effective in dispelling and dissipating negativity and unwanted energetic fields.

Black Obsidian is a naturally occurring volcanic glass that has been used by prehistoric man by fashioning into tools, primarily weapons.  The association with Black Obsidian as a protective weapon is more than symbolic if you can make the connection with your stone as part of your energetic defence toolkit.  Black Obsidian is a highly energetic stone, yet grounding, being associated with your root chakra.  Black Obsidian can provide comfort in times of high stress and allow you to see things more clearly.

Stone carved into the human skull form is a tool that can be used with meditative practice to expand your consciousness.
