Peridot - A stone to totally shield your energy. When you wear peridot nothing gets in or out. This makes it ideal for protection of all sorts, including cords and psychic attack.
Because it is such a powerful shield you must take it off from time to time and allow your energy to circulate. A stone of the senses, peridot puts you in contact with the senses, how they function and how we are tied into a ‘sensual’ existence.
It is a stone for the Heart Chakra, assisting in opening to love and relationships.
