Fluorite is an upper chakra stone. It comes in many colours - clear, green, purple, and teal are the most common ones. The colour of the stone indicates the chakra it is most helpful with. Some of the properties of fluorite include aiding in discovering one's path, seeing the bigger picture, focus and organization, studying/learning, and cleansing the aura.
