I'm a mix of 6mm Tourmaline and 8mm Rutilated Quartz with silver plated focal and silver plated spacers. Tourmaline is a sought after stone because it is told that it promotes inspiration and happiness, reduces fears and helps to build self-confidence. Many believe it gives balance to the left and right side of the brain and has the ability to shield the wearer from psychic attacks. Quartz raises the vibrations of the Tourmaline. This is a stretch bracelet made by hand, each a bit unique.
