Mahogany Obsidian is a rare variety of Obsidian found primarily in the Western United States. It is named after mahogany trees, which share a similarly striking red-brown color. It gets its pretty red-brown coloring from a higher-than-normal concentration of Iron. Like other Obsidians, it is formed from rapidly cooling lava following a volcanic eruption. Most Mahogany Obsidian comes from Glass Buttes, Oregon. These beads have a an excellent polish and are cut very evenly.
