Mahogany Obsidian is a rich brown colour with black spots. It is associated with the planet Pluto - the greek god of the underworld and the keeper of hidden treasure. This is a grounding stone that also has a fiery element to it and has a gentle energy that will help protect and ground the person who owns it. It is said to work well with all chakras but especially the first.
Mahogany Obsidian is found anywhere volcanic or where volcanic activity has occurred. Some of the places it comes from today are Japan, South America, Afghanistan, Mexico, and parts of the United States. In the San Carlos Apache Reservation in Arizona, United States, a particular variety of Mahogany Obsidian called Apache Tears is produced.
