Size: Most stones are ¾ inch to 1¼ inch Crystals work with your own energy. Because of the composition and make-up of crystals they have the unique ability to harness and transfer energy. A crystal is a solid material whose constituents are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. Crystals are built out of atoms. Each crystal has its own natural vibration and attributes, which can activate and promote both emotional and physical healing in oneself and others – that’s if the frequency is the right match for you and your needs.
