About Fire Obsidian
Fire Obsidian forms when microscopic layers inside volcanic glass refract light like living prisms beneath the surface. Unlike surface sheen obsidian, true fire obsidian shows depth fire that shifts with movement, making every piece unique and increasingly difficult to source in larger polished sizes.
Double-sided fire pieces like this are especially desirable for designers.
