Rainbow Obsidian earned its name from the chatoyant, rainbow effect of light refracting off of the air buddles inside of the stone. Like all obsidian, it is made up of volcanic glass. Rainbow Obsidian is said to help alleviate fears at home or work that seem overwhelming or that we seem to not be able to overcome. It can bring back good luck and bring happiness to the user. Additionally, as it operates primarily on the root chakra, Rainbow Obsidian is known as a grounding and protective stone.
