Peridot carries a beautiful green energy that activates the Heart Chakra, located near the center of the breastbone. It regulates our interaction with the external world and controls what we embrace and what we resist. It gives us the balancing ability to be ourselves within the environment. When the Heart Chakra is out of balance we may feel either controlling or controlled in a relationship, and become critical of the little foibles of others. We may find ourselves having inappropriately strong emotional responses to everyday external stimuli. Green crystal energy is used to resolve blockages and to re-balance the Heart Chakra, helping us understand our own needs and emotions clearly. We can deal with the ebbs and flows of emotional relationships, understand their cyclic nature, and accept the changes.
