Amethyst stimulates the Third Eye, Crown, and Etheric Chakras enhancing cognitive perception as well as accelerating the development of intuitive and psychic ability. It initiates wisdom and greater understanding and is a stone of comfort for those grieving the loss of a loved one. It is also the stone of sobriety as amethyst is derived from the Greek word améthystos (αμέθυστος), meaning "not intoxicated".
