Mahogany Obsidian
The Keeper of Abundance
Also known as: Mountain Obsidian, Mahogany Glass
About the stone
Mahogany obsidian is natural volcanic glass with reddish-brown patches or bands against black, formed when silica-rich lava cools rapidly; microscopic hematite crystals give it its mahogany coloring. Its history belongs to the broader use of obsidian for prehistoric cutting tools and ornaments rather than a separately documented ancient gemstone tradition. Sources include Mexico and the western United States—especially Glass Buttes in Oregon and sites in California, Arizona, and New Mexico—with a scientifically studied occurrence near Tolcsva, Hungary. Also sold as mahogany glass, red-brown obsidian, or occasionally mountain mahogany obsidian, it is a descriptive variety, not a separate mineral species. Modern crystal lore associates it with grounding, protection, resilience, and releasing negative patterns.

Care and handling
Mahogany Obsidian is natural glass, so it is brittle and chips or cracks if dropped or struck; broken edges can be sharper than steel. Handle carefully and keep it from small children. Clean with lukewarm water and a soft cloth, then dry it. Avoid ultrasonic cleaners, steam, sudden temperature changes and harsh chemicals. Store it where it will not knock against other stones.
Individual experiences with Mahogany Obsidian vary, and its effects are personal and not guaranteed. Use it with mindful intention, and let it remind you that you are worthy of comfort and care.
