Which metals should I avoid in jewelry?

Nickel is the metal most often linked to skin reactions. If your ears or fingers itch, turn red or blister after wearing a ring, earrings or bracelet, nickel may be the cause. Many cheap alloys contain it, so look for items marked nickel-free if you are prone to sensitivity.

Brass and copper are not usually dangerous, but they do tarnish and can leave a green mark on your skin. This is harmless for most people, but it can be annoying on your wedding day or in photographs.

Plated metals are another group to be careful with. The plating is only a thin surface layer and will wear off with time. Once it is gone, the base metal underneath may show or react with your skin.

For long-lasting jewellery, solid gold, platinum, palladium and titanium are much better choices. They resist tarnish and can be resized or repaired. If you are unsure about a piece, ask the seller what the metal content is and whether it is suitable for sensitive skin.
