Some people ask "why buy steel jewelry?" Steel,while it may not be considered a precious metal, is far more durable andaffordable than silver or platinum. The durability of stainless steel is due to the Chromium coating that isactually chemically bonded to the steel. What this virtually invisible coatingdoes is protect the steel underneath from oxidation (tarnishing and rusting).It also protects against scratches by taking the initial impact of a scratchand then resealing itself. This phenomenon is called passivation. Passivationis the spontaneous formation of a hard non-reactive surface film that inhibitsfurthercorrosion.
