White gold and nickel: what to check before you buy

White gold isn't naturally white. Gold is yellow. To make it look silver-toned, jewelers alloy the gold with white metals — usually nickel, palladium, or a combination — and then plate the finished piece with rhodium, an even brighter white metal in the platinum family, to hide any residual yellow tone in the alloy underneath.

The nickel is the part that matters. Nickel allergies affect somewhere between 10 and 20% of adults, depending on the study, and skew female. If you fall into that group, white gold jewelry can trigger a rash that persists for as long as the piece is worn — often a red, itchy band exactly where a ring sits, or a spot of irritation under a pendant.

This is worth knowing before you spend on white gold, especially for pieces meant to be worn constantly.

Why most American white gold contains nickel

Nickel is a very good white-metal alloy. It's cheap, workable, and produces a strong, hard white gold that holds a setting well. American jewelry manufacturing has used nickel-based white gold as the default for decades. Unless a jeweler specifies otherwise, that's what you're getting.

Palladium-based white gold exists as an alternative. Palladium is more expensive than nickel — at times 4–6× the price of gold, depending on the market — which is why palladium white gold costs more. It's also naturally a whiter white, which means the finished piece needs less rhodium plating and less frequent re-plating over time. European jewelers use palladium alloys more commonly than American ones.

The karat doesn't matter. A 10k, 14k, or 18k white gold ring can all contain nickel. The percentage of nickel varies — smaller share in higher karats, larger in lower — but the presence of it is what matters for an allergic wearer, not the amount.

What rhodium plating actually does

Every white gold piece is plated in rhodium after fabrication. Rhodium is a member of the platinum family, brilliantly white and hypoallergenic. The plating does two things: it makes the finished piece look pure white (masking any warm undertone in the underlying alloy), and it creates a thin protective layer between the wearer's skin and the nickel underneath.

For most people, rhodium plating is enough to prevent a reaction. As long as the plating is intact, no nickel is touching the skin.

But rhodium plating wears off. On a ring worn daily, especially on the underside of the shank where the skin contacts the metal most, the plating typically wears through in 2–5 years. Once it does, the nickel-containing alloy is exposed, and a nickel-sensitive wearer starts to notice symptoms.

Re-plating is a nominal service — usually $60–$150 depending on the piece and the jeweler — but it's a maintenance cost that platinum, palladium white gold, or yellow gold pieces don't have.

Symptoms of a nickel reaction

Nickel allergy shows up as contact dermatitis: red, itchy, sometimes blistered skin where the metal has been touching. On a ring finger, it's a distinct band exactly where the ring sits. On a pendant, it's a spot where the pendant rested. Symptoms usually appear within hours to days of prolonged contact and resolve within a week or two of removing the piece.

If you've never had a metal allergy before, you might not know you have one. Nickel sensitivity can develop at any point in life, and often does after prolonged exposure to nickel-containing items (jewelry, watch backs, jean buttons, glasses frames). Some people become sensitive in their 30s or 40s after decades of no reaction.

The question worth asking up front

The direct question is: "Does your white gold contain nickel?"

If the answer is yes (which it will be, most of the time), the follow-up is: "Do you offer palladium white gold or platinum as an alternative?"

Most bespoke jewelers can source palladium white gold on request. It costs 15–25% more than nickel-based white gold, and it's worth the difference for anyone with a confirmed nickel allergy or a family history of one.

Platinum is a stronger option for a confirmed allergy. It's pure white without plating, doesn't oxidize, and is naturally hypoallergenic. The tradeoff is cost — platinum runs roughly twice the price of 14k gold — and weight, which some people love and others find heavy.

Alternatives if the answer is no

If nickel is confirmed and neither palladium white gold nor platinum is an option, the alternatives are yellow gold or rose gold. Neither contains nickel in typical alloys. Rose gold is copper-based; yellow gold is gold plus small amounts of silver and copper. Both are safe for nickel-allergic wearers, and both look different enough from white gold that the substitution is a real aesthetic decision, not a workaround.

Sterling silver is hypoallergenic and inexpensive, but tarnishes and softens under daily wear. Better for occasional pieces than for engagement rings.

For pieces already owned

If you already have a nickel-containing white gold piece and you're starting to react, the options are: re-plate the piece in rhodium (short-term fix, lasts 2–3 years), remake the piece in platinum or palladium white gold (expensive but permanent), or apply a thin barrier — clear nail polish on the inside of a ring is a common home fix that lasts a few weeks per application.

The nail polish trick isn't a long-term solution, but it can extend the life of an existing piece while you decide what to do.

I've had clients come back years after a purchase from another studio, wondering why the ring they loved on their wedding day suddenly gives them a rash. It's almost always this — plating worn through, nickel exposed, and no one had said anything about it at the counter.

At Catherine Peck, standard white gold contains nickel. Palladium-based white gold is available on request for bespoke commissions. Anyone with a known nickel sensitivity should note it before ordering — the studio can walk through options and pricing before the piece is designed.
