Stainless steel remains "stainless" if it contains at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface.

The first number is the amount of chromium that is contained in the stainless, i.e., 18 is 18% chromium. The second number is the amount of nickel, i.e., 8 stands for 8% nickel. So 18/8 means that this stainless steel contains 18% chromium and 8% nickel. 18/10 is 18% chromium and 10% nickel. The higher the numbers the more corrosion resistant the material.

The 300 series (which contains nickel) is NOT magnetic. The 400 series (which just contains chromium and no nickel) ARE magnetic.

The stainless Steel jewelry in our store is 316L. The main features of 316L is immune from sensitization. Stainless steel has in recent years been used increasingly in jewelry. The benefits include a high resistance to corrosion which prevents rust, a resistance to high temperatures, long term durability and a bright, easily maintained surface providing for a modern and attractive appearance. Stainless steel is also quite easy to clean and does not oxidize over time as does other types of semi-precious materials. These rings are comfortable and fashionable, a complimenting accesory to any style.
