Rainbow Obsidian is formed when lava cooled at different times & captured Magnetite nanoparticles within these layers. The Magnetite nanoparticles cause multicolored iridescence that shines bright when any light hits it. Obsidian is a strongly protective stone, it forms a shield against negativity. 
 
Note to buyers: I'm a self-taught silversmith. I hand-make & hand-finish each piece with lots of love. No two items are the same.
