Mahogany Obsidian is another of the more unusual varieties of Obsidian. Mahogany Obsidian may be entirely a reddish-brown stone, or may occur as reddish-brown streaks within Black Obsidian. The reddish-brown colour is likely due to oxidized iron within the stone. Mahogany Obsidian is a hardness 5 and is frequently used for carved decorations and in jewelry. However, as with all Obsidian, be careful with grinding it and always do so wet as the dust can be hazardous. Also, as it is a glass, be careful when handling it has it can have razor sharp edges. Mahogany Obsidian is found in Arizona, California, Utah, and Oregon.
