Ask any honest jeweller and you'll get the same answer: yes, 925 sterling silver can tarnish. But that sentence needs the rest of the story, because tarnish is not damage, it's not permanent, and with a handful of small habits it's almost entirely avoidable. Here's what's actually happening to your silver, and how to keep every piece as bright as the day it arrived.
What "925" actually means
Pure silver is too soft for jewellery you wear every day. So sterling silver blends 92.5% pure silver with 7.5% copper, which gives the metal its strength while keeping the white brilliance silver is loved for. That 92.5 is where the "925" hallmark stamped inside quality jewellery comes from, and it's the international standard for genuine sterling silver. Every piece at DIAMORAY is 925 sterling silver, hypoallergenic and nickel free.
Why does sterling silver tarnish?
Tarnish is a natural chemical reaction, not a flaw. Silver, and especially the small amount of copper in the alloy, reacts with sulphur compounds in the air. The result is a thin surface layer that starts as a faint yellow warmth and deepens toward grey if it's left alone for months.
A few things speed the reaction up: humidity, perfume and hairspray, chlorinated water, sweat, and long stretches in open air. That's why a ring worn daily and wiped now and then often stays brighter than one forgotten in a bathroom drawer.
Does tarnish mean my jewellery is low quality?
The opposite, usually. Genuine sterling silver tarnishes precisely because it's real silver; that's the metal chemistry doing what silver has done for thousands of years. Cheap costume jewellery made from base metals doesn't tarnish the same way, it corrodes, flakes or turns skin green. A faint tarnish that wipes away with a cloth is one of the quiet signs you're holding the real thing. Modern sterling silver, including DIAMORAY pieces, is also finished with a protective anti-tarnish treatment that slows the reaction dramatically, which is why well-made 925 jewellery can go months looking untouched.
How to stop silver tarnishing
Prevention is mostly about what silver touches and where it sleeps:
- Last on, first off. Put jewellery on after perfume, lotion and hairspray have dried, and take it off before they're reapplied.
- Skip the pool and the shower. Chlorine is silver's least favourite chemical, and hot soapy water leaves residue in settings.
- Wipe after wearing. Ten seconds with a soft cloth removes the day's oils before they can react.
- Store it dry and closed. A small pouch, zip bag or lined box beats an open dish. A silica gel sachet in the box absorbs the humidity that drives tarnish.
- Wear it. Counterintuitive but true: gentle daily wear and the light friction that comes with it keeps silver brighter than long-term storage in open air.
How to clean sterling silver that has tarnished
Caught early, tarnish comes off in a minute:
- Soft cloth first. A lint-free or dedicated silver cloth removes light tarnish with a few gentle passes.
- Warm water and mild soap. For jewellery set with stones, a short soak in lukewarm water with a drop of washing-up liquid, a gentle going-over with a baby-soft brush, a rinse and a thorough pat dry brings back both metal and sparkle.
- Avoid the aggressive stuff. Toothpaste, baking soda scrubs and harsh chemical dips are abrasive or too strong for fine settings, they can scratch the finish and dull stones.

A note on gold plated 925
Gold plated sterling silver, like the gold versions of our rings and earrings, carries a layer of gold over the same 925 base. The gold itself doesn't tarnish, so care is even simpler, but gentler: wipe with a soft cloth only, keep it away from perfume and pools, and skip polishing cloths made for bare silver, which are mildly abrasive and made to lift a layer you want to keep.
And the stones?
Cubic zirconia doesn't tarnish, fade or cloud on its own; what dulls a stone is a film of skin oils and soap sitting on its facets. The same lukewarm water and soft brush that clean the silver bring a CZ straight back to its diamond-like fire, which is most of the reason a two-minute clean makes a necklace or bracelet look brand new.
Frequently asked questions
Can I shower with sterling silver?
Occasionally won't ruin it, but soap film and hot water speed up tarnish and dull stones, so the habit to build is jewellery off before the bathroom.
Can I sleep in it?
You can, and many people do. The real risks are mechanical, chains kinking and earring posts bending, rather than tarnish.
How often should I clean silver jewellery?
A quick wipe after wear, and a proper two-minute clean every few weeks for daily pieces. Tarnish removed early never gets the chance to build.
Is tarnish harmful to skin?
No. It can occasionally leave a grey mark on skin, which washes off, but sterling silver itself is hypoallergenic and safe for sensitive skin.
Will my 925 jewellery last for years?
With the habits above, absolutely. Sterling silver is a metal people pass down; it just asks for ten seconds of attention after a day's wear.
