Basically, a super thin coating that increases shine, is hypoallergenic and can add any colour or more expensive precious metals (gold, rhodium, sterling silver or platinum) to the steel. Ion Plating IS PVD (Physical Vapor Deposition) - a vacuum coating process where gold is vaporized in a vacuum and deposited onto the surface of stainless steel. This produces a brilliant shine to the stainless steel. PVD uses titanium nitride which gives an extremely durable coating, resistant to corrosion from sweat and regular wear. The jewellery remains bright and shiny for a very long time. 316L Stainless Steel is making stunning jewellery. Stainless steel is an alloy, primarily iron mixed with Chromium. Chromium serves as a protective layer. Chromium decreases oxidation, keeping your jewellery shiny for much longer. Protects also from any possible allergic reactions to trace amounts of other metals in the stainless steel. No corrosion No tarnishing No rusting Scratch-resistant End result? Sleep, swim and go to work with it. Caring for it: Wash with a little soap and water. We love it. And so will you
