316L is the highest grade of stainless steel used in the jewellery market. It is so good at resisting fade, rust, and corrosion, that it is used in architecture as well as in marine environments. At the same time, it is safe to use for medical purposes inside the body. For this reason the stainless steel rings we carry are made with this same grade of steel. It will not fade, change colour, or leave stains on your body. It doesn't even require any maintenance to keep it looking new. Our competitive wholesale pricing along with our standard for high quality is what consistently sets us apart from the rest.
