Anti-Tarnish Jewellery Explained: What It Is and Why It Matters

Anti-tarnish jewellery is made so it doesn't darken, fade or turn green with everyday wear. Usually that means a base metal that doesn't react with sweat and air, such as stainless steel, under a well-bonded gold finish. It slows tarnish a great deal, but it isn't magic: how long it lasts depends on what's underneath and how the gold was applied.
