About this stone

Black Obsidian with iridescent rainbow sheens created by microscopic mineral inclusions. Rainbow Obsidian absorbs negative energy, reveals hidden truths with gentleness, and brings light to darkness. It heals the aura after trauma or grief.

Geology · Formation

How it forms: Magnetite inclusions in volcanic glass.

Rainbow Obsidian is a volcanic glass that reveals a secret rainbow when light hits it. It forms during volcanic eruptions when silica-rich lava cools. Tiny inclusions of magnetite or other iron-rich minerals are oriented in thin layers within the glass. The Result: A seemingly black stone that flashes rings of purple, green, and gold when held to the sun.
