316L is the highest quality of Surgical Stainless Steel in the jewelry market and that is exactly what all of our jewelry is made from. It won't change color, leave staines on your body, and it does not require any maintenance to keep it looking brand new. In fact, it is so good at resisting fade, rust and corrosion, that this grade of steel is often used in marine environments and since it is nickel free it is also used in surgical procedures.
