Aquamarine is a wonderful stone for meditation because it calms the minds, clears the aura and aligns the chakras. It also helps us to release judgement and encourages us to take responsibility for our own actions.
Luc Bourgault in his book Secrets of Crystal Healing recommends holding or wearing aquamarine to help you overcome your fears. "You can confront fear," he says, "because it is cowardly. All the time that you run away from it, it will follow you like a shadow. But the moment you turn and face it, it will be the one to run away."
Aquamarine would be a great stone for a therapist, school counselor, or psychologist to have in his/her office because it helps the patient to speak truthfully, face fears and accept responsibility.
