Does gold-plated jewelry tarnish?

Gold itself does not tarnish. But gold-plated jewelry is a thin layer of gold bonded over a base metal — usually brass or stainless steel — and that base metal does react with air, moisture, and skin. Once the plating thins in the places you touch most, the metal underneath starts to show as a dull, darker cast.

That is not a defect and it is not a sign of a cheap piece. It is simply how plating works, on a $28 chain and on a $400 designer one alike. What changes between them is how thick the plating is and how well the piece is looked after.

With regular wear and reasonable care, expect one to two years of bright, unchanged colour from a well-plated piece. Worn every single day, in and out of showers, pools, and perfume, the same piece can dull in a matter of months.

The difference is almost entirely habit, not price. The people whose jewelry still looks new after two years are not doing anything elaborate — they simply take it off before water and put it on after perfume.

Brass tarnishes through oxidation: copper in the alloy reacts with oxygen and moisture and forms a dark film on the surface. On a plated piece, that film only appears once the gold layer has worn thin enough to expose the base.

The things that speed this up, in rough order of damage: chlorine and salt water, perfume and hairspray sprayed directly onto a piece, sunscreen and thick lotions, hot showers, and sweat left to dry on the metal overnight. Everyday air does very little by comparison — most tarnish is chemistry, not time.

Warm water, one drop of gentle dish soap, and a soft cloth. Dip the cloth rather than soaking the piece, wipe along the surface without scrubbing, rinse briefly in clean water, then pat completely dry with a microfiber cloth before it goes away.

Never use toothpaste, baking soda, vinegar, ultrasonic cleaners, or polishing compounds on plated pieces. Every one of those works by removing a microscopic layer of metal — which is exactly the gold layer you are trying to keep. They will make a dull piece look bright once, then leave it worse than before.

For a piece that has already gone dark, a plain jewelry polishing cloth (dry, no compound) lifts most surface film. If the darkness stays after that, the plating is gone in that spot and cleaning will not bring it back — replating through a local jeweller is the only real fix.

Most of the jewelry we carry is gold-plated stainless steel rather than plated brass. Stainless steel does not oxidise the way brass does, so even when the plating thins the piece underneath stays silver-bright rather than turning dark green or black — and it is far kinder to sensitive skin.

If tarnish has burned you before, that is the material to look for on any product page, ours or anyone else's. It is worth the few extra dollars.

Last on, first off — jewelry goes on after perfume, sunscreen, and lotion have dried, and comes off before you wash your face at night.

No water. No showers, no pools, no ocean, no washing dishes. Water alone is not the enemy; what is dissolved in it is.

Wipe after wearing. Ten seconds with a soft dry cloth removes the skin oils and sweat that do the slow damage overnight.

Store pieces apart, in soft pouches, somewhere dry. Metal rubbing on metal wears plating faster than wearing it does.

Rotate what you wear. A piece worn three days a week outlasts the same piece worn seven, by roughly the margin you would expect.
