Amethyst is a stone of spiritual protection and purification. It stimulates the third eye, crown and etheric chakras and is an aid to meditation, helping one to move into higher states of consciousness. It facilitates the creation of an energetic "shield" around the body to protect from negativity. It can counter addictive behavior and can help one identify the root cause of one's disease or imbalance.
