Rainbow Obsidian
The Light Shower in the Dark
Also known as: Iris Obsidian, Rainbow Sheen Obsidian, Fire Obsidian
About the stone
Rainbow obsidian is a natural volcanic glass that appears dark until angled light reveals bands of green, purple, blue, or gold; in well-studied Mexican material, these colors result from light interacting with aligned microscopic crystals of hedenbergite. Obsidian generally has been used since prehistoric times for tools, ornaments, and mirrors. A major commercial source is the La Revoltosa mine in Jalisco, Mexico; iridescent obsidian is also reported from Glass Buttes, Oregon. Alternative names include “rainbow sheen obsidian” and “iris obsidian”; “fire obsidian” describes a related iridescent material whose optical structure can differ. Modern crystal lore associates rainbow obsidian with hope, emotional renewal, and protection, while ancient Aztec mirror traditions concern obsidian more broadly—not specifically the rainbow variety.

Care and handling
Rainbow Obsidian is natural glass, so it is brittle and chips or cracks if dropped or struck; broken edges are very sharp. 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. Its iron-bearing inclusions may be slightly magnetic, so store it away from sensitive electronics.
Individual experiences with Rainbow Obsidian vary, and its effects are personal and not guaranteed. Use it with mindful intention, and let its colors remind you to find light in the dark.
