Amber is not a crystal, as it is petrified tree sap, and therefore a resin. Amber has a warm and bright energy, encourages self-esteem, strength, and feelings of security. It activates the life-force energy and is helpful for empaths because it cleanses and transmutes negative energy. Amber also encourages positivity, helps with anxiety, and grounds excess energy.
