What is nickel in jewellery?

Definition
Nickel is a hard, silvery metal used in jewellery primarily as an alloy ingredient, added to white gold to achieve its pale colour and hardness, and widely used in fashion and costume jewellery. It is practical from a metalworking perspective but is one of the most common causes of contact dermatitis, a skin reaction that shows up as redness, itching or a rash where metal touches the skin. Once a nickel allergy develops it tends to be permanent, so many people actively seek out nickel-free pieces, particularly in earrings.
Frequently asked questions
- How do I know if my jewellery contains nickel?
- Fine jewellery in solid gold or platinum is less likely to contain nickel, though some white gold alloys still use it. Fashion jewellery and silver-coloured costume pieces are common sources. Nickel-free pieces are often labelled explicitly, and nickel test kits are available for checking suspect pieces.
- What can I wear instead of nickel if I have a reaction?
- Solid gold (9ct, 14k or 18ct), platinum, titanium and surgical-grade stainless steel are all good alternatives. Sterling silver is often fine, though some sterling alloys include small amounts of nickel. Look for pieces specifically marked as nickel-free or hypoallergenic.
- Is nickel in white gold?
- Older and cheaper white gold alloys often used nickel to achieve their pale colour. Many jewellers now use palladium or other metals instead, which is gentler for sensitive skin. If white gold and skin reactions are a concern, ask your jeweller which alloy they use.
