Dumortierite
Dumortierite is a stone for accessing higher guidance and clarity to transcend difficulties. It enhances all mental activities including concentration and focus. It is very useful for learning and retaining new information. Dumortierite teaches you to stand up for yourself, and it will help you to take control of your own life and increase your level of patience. It helps work through issues associated with addictions, habits or limiting beliefs.
Dumortierite helps to amplify psychic/intuitive abilities and works with the Brow or Third Eye Chakra.
