Does Sterling Silver Tarnish?
Yes. Sterling silver is 92.5% silver, and the silver reacts with sulphur in the air. That reaction is what causes tarnish. It's not damage, and it's not permanent. A quick polish brings it straight back.
Does gold tarnish in the same way?
No. Solid 9ct and 18ct gold don't tarnish the way sterling silver does. It's one of the reasons I work in both metals rather than one.
Why silver tarnishes
Sterling silver is 92.5% silver and 7.5% other metals, usually copper. That's what the 925 stamp means. Pure silver is too soft for most jewellery, so the copper is added for strength. The trade-off is that copper reacts with sulphur in the air and on your skin, and that reaction is what you see as tarnish: a dull yellow tone first, then grey, then nearly black if it's left long enough.
So tarnish isn't dirt sitting on the surface. It's a thin layer of the metal itself reacting. This is why a quick wipe doesn't always shift it and why it comes back. It's also why no sterling silver, from any maker at any price, is immune to it.
What speeds it up silver tarnishing?
A few everyday things accelerate it. Sulphur is the main culprit, so anything that carries it will darken silver faster. The usual ones are perfume, hairspray, lotions, and household cleaning products. Sweat and the natural acidity of your skin play a part too, which is why some people tarnish silver faster than others through nothing more than body chemistry.
Damp is the other big factor. Storing silver in a humid bathroom, or putting it away while it's still damp, gives tarnish the conditions it likes. Swimming pools and the sea will both dull silver quickly, chlorine especially.
How do i stop sterling silver tarnishing?
The single most effective thing is to wear it. Skin contact and the friction of normal wear keep silver bright, which is why the pieces you wear most are rarely the ones that go dark. The pieces that tarnish badly are usually the ones left sitting in a drawer for months.
Beyond that, a few simple habits help. Put jewellery on last, after perfume and lotion, not before. Take it off before swimming, showering, and cleaning. When you store it, keep it somewhere dry, ideally in a sealed bag with the air pushed out, since less air means less reaction. An anti-tarnish strip in the bag helps for pieces you won't wear for a while.
How to bring the shine back
When silver does tarnish, it's easily reversed. For light tarnish, a proper silver polishing cloth is all you need. These are impregnated with a mild polish and will lift the dullness in a minute or two of gentle rubbing. Keep one in the drawer and most pieces never get the chance to darken badly.
For heavier tarnish, a dedicated silver cleaner works, used sparingly and according to the instructions, then rinsed and dried fully. Avoid abrasive pastes and rough cloths on anything with a delicate finish, and be careful around set stones, since some cleaners don't suit certain gemstones.
One thing to know: if a piece has a deliberately oxidised or blackened finish, like the darker work in some of my pieces, don't polish that away by accident. That darkening is intentional and part of the design, and aggressive cleaning will strip it.
Does 925 silver tarnish faster than other silver?
No slower or faster than any other sterling silver. 925 is just the stamp that confirms it's 92.5% pure.
When you can't shift it
If you've tried a cloth and a cleaner and a piece still looks tired, bring it to me or any jeweller. Professional cleaning and repolishing will return it to as-new, and it's a small job. Sterling silver is one of the easiest metals to restore, which is part of why it lasts so well across a lifetime.
Tarnish, in the end, is just proof you're wearing real silver. It's a feature of the material, not a fault in the piece.
