Rainbow obsidian is a lightweight volcanic glass with iridescent properties, giving it a subtle cat's eye glow in sunlight. Every movement reveals a subtle sheen, with muted rainbow colors moving on the stone. Microscopic crystals and bubbles of mica in the volcanic glass create the multicolored effect.
