Amethyst is a powerful and protective stone. It guards against psychic attack, transmuting the energy into love and protecting the wearer from all types of harm, including geopathic or electromagnetic stress and ill wishes from others.
For serenity of the mind
Its high vibration blocks negative, stressful energies and stimulates serenity of the mind. Placing an amethyst on your nightstand or under your pillow is known to protect you from nightmares.
