New Gold Bracelet. High quality Stainless steel jewelry is strong, durable and rust-resistant. Steel contains carbon, nickel and chromium. In order for steel to be considered stainless, it must contain at least 12 percent chromium. Chromium makes the steel stainless by creating an invisible top layer that prevents oxygen from rusting and otherwise corroding the steel surface. This means that stainless steel jewelry will not rust or tarnish.
