Amethyst amplifies/magnifies the energy of other crystals, and works for protection, and physical, mental, and emotional balance.
Is meant to be worn, preferably touching the skin, or held in meditation. Amethyst, used for purification rituals historically, encourages consciously dealing with perception - helping one face up to all experiences, whether pleasant or unpleasant. Amethyst also helps one move forward in life, cope with change and responsibility, and calms nerves, passion, tension, oversensitivity, grief, and balances emotional energy.
