8mm Aqua Terra Jasper and Sterling Silver. Will fit wrist size of 7". Aqua Terra (meaning Water Earth) is a wonderful stone for helping one find inner peace, clarity, love and compassion, helps with the alignment of the physical and “Light” bodies and is an excellent stone for emotional healing. Silver, when used with gemstones, is able to both attract and retain those qualities which are emitted by the stone. The silver provides a steadying influence. It performs a balancing act by drawing negativity from the body while transferring the positive energies of other minerals.
