Mahogany Obsidian is a type of Obsidian with Hematite or Magnetite inclusions within, giving it its red, brownish color.
 
Mahogany Obsidian is often used to remove energy cords between people that sap energy and violate boundaries. It is also used for protection from psychic attacks by those who wish to harm (or those who don’t even intend to but their energy is negative or aggressive and might inadvertently do so). It is also said to strengthen the aura, protecting against repeated problems. In physical healing it is thought to be helpful in detoxifying organs and tissues, increasing liver and kidney function, and relieving pain.
