Yes, sterling silver tarnishes, and every piece of it does eventually. Tarnish is a thin film that forms when the copper in the alloy meets sulphur in the air, on your skin, and in the products you put on before you leave the house. It sits on the surface, it is not corrosion eating into the metal, and it comes off with a clean cloth in a few minutes.
Does sterling silver tarnish?
Sterling silver tarnishes because it is an alloy. Pure silver is too soft to hold a ring shape, so it is mixed with a small amount of copper for strength, and copper reacts with sulphur compounds in air, sweat, rubber, wool and plenty of household products. The reaction produces silver sulphide, which is dark, and it builds up as a film on the outside of the metal.
The important part is where it stops. Tarnish is surface level, so a tarnished ring has lost no material and taken no damage. Polish the film away and you are back to the same metal you started with. Some people tarnish jewellery in a fortnight and others go months, and the difference is body chemistry, climate and what you handle.
Why is my silver ring turning black?
A silver ring turns black because tarnish has built up faster than your skin and clothes rub it off. Black is heavy tarnish, several stages past the first yellow tint and the grey-brown that follows.
A few things speed it up. Humid coastal air. Sweat, especially if you train in the ring. Sunscreen, aftershave, hairspray and moisturiser, which all contain compounds silver reacts with. Storing it in a bathroom, where steam and product residue sit in the air all day.
Blackening in the recesses of an engraved piece is different again. Deep areas hold tarnish because nothing touches them, which is why a signet with cut detail darkens in the lines first while the face stays bright.
What is 925 sterling silver, and is it good quality?
925 sterling silver is 92.5% pure silver and 7.5% other metals, usually copper. The 925 stamp is the international standard for solid sterling, and it is a genuine quality marker rather than a marketing term. Anything sold as sterling silver should meet it.
It is good quality for jewellery you actually wear. The copper is what lets it hold a polish, take a setting, and survive being knocked against a desk. Fine silver at 99.9% is brighter and softer, and a ring made from it would bend out of round. The trade off is tarnish, the price of a metal hard enough to be useful. Every silver piece we make is solid recycled 925, cast in Bali using traditional lost-wax casting, and the range is in recycled sterling silver.
Is recycled silver the same quality as newly mined silver?
Yes. Recycled silver is refined back to the same 925 standard as newly mined silver, and once it is refined there is no way to tell the two apart in the finished piece. Same purity, same hardness, same shine, same tarnish behaviour.
The difference is where the raw material came from. Recycled silver is reclaimed from existing sources and refined again instead of being pulled out of the ground, which is a sourcing decision rather than a compromise on the metal. It is what we use across the rings range, and as a B Corp certified brand, material sourcing is part of what we are assessed on.
Can you shower or swim in sterling silver?
Water on its own will not hurt sterling silver. The problem is what is in the water. Chlorine attacks the alloy and can dull or pit the surface over time, and saltwater accelerates tarnish and leaves residue in chain links and settings.
A quick shower is unlikely to cause damage, though soap film builds up in engraving and around stones and dulls the finish. The sensible habit is to take silver off before the pool, the ocean and the spa, and dry it properly if it does get wet.
Our lifetime craftsmanship warranty covers manufacturing faults. It does not cover chemical exposure, which includes chlorine, saltwater and perfume, so a ring dulled in a pool is a care issue rather than a warranty claim. If you are unsure about a piece, talk to support.
Do sweat, the gym and the ocean damage silver?
Sweat does not damage sterling silver, but it does tarnish it quickly. Sweat carries salt and sulphur compounds, and a session in the gym leaves both on the metal, which is why gym-worn rings and chains dull faster than office-worn ones.
The ocean is harder on jewellery than the gym. Saltwater gets into chain links and under settings, dries there, and keeps working long after you have towelled off. Cold water also shrinks your fingers, which is a common way to lose a ring in the surf.
Neither is a disaster. Rinse in fresh water, dry it fully, and the salt is gone. The bigger risk in a gym is mechanical: a loaded bar will flatten a cuff or bracelet and bend a band out of round, and impact damage is not covered by the warranty.
Does silver turn your finger green, and why?
Sometimes, yes, and it is the copper in the alloy doing it. When copper reacts with acids in your sweat it forms copper salts, which are green, and those transfer to the skin under the ring. It washes off and it is not a sign that the silver is fake or low grade.
Some people get it and most never do. It shows up more in hot weather, on hands that sweat, and when hand cream or cleaning products sit trapped under a band all day. If it happens to you, take the ring off before washing up, dry your hands before putting it back on, and clean the inside of the band regularly.
How do you clean tarnished silver at home?
Warm water, a drop of mild dish soap, and a soft cloth. Let the piece sit in the water for a minute, work gently around the detail with a soft toothbrush, rinse, and dry it completely with a lint-free cloth. That removes sweat, soap film and product residue.
For tarnish film, use a jeweller's polishing cloth. It is impregnated with a fine polishing agent, so you rub the surface lightly until the grey lifts and comes off onto the cloth. A minute or two is usually enough.
What to keep away from your silver:
- Toothpaste. Abrasive. It puts fine scratches into a polished surface.
- Scourers, steel wool and paper towel. All scratch. Cloth only.
- Harsh chemical dips. They strip everything fast, including oxidised detail, and leave the surface flat.
- Ultrasonic cleaners on stone-set pieces. The vibration can loosen a setting or damage a soft stone.
Our full routine, including chains and vermeil, is in caring for your jewellery.
What about stone-set rings and oxidised finishes?
Stone-set and oxidised pieces need a gentler hand than a plain polished band. On a stone-set ring, clean around the setting with a soft brush and mild soapy water, dry it thoroughly so no moisture sits under the stone, and skip the ultrasonic cleaner.
Oxidised and blackened finishes matter more again, because that darkness is deliberate. An oxidised finish is controlled tarnish, applied to sit in the recesses and give a piece depth. Polishing cloths and dips are designed to remove exactly that, so heavy polishing lifts the finish and leaves the design looking flat. Wipe the raised areas only and use soapy water instead of polish. The same goes for gold vermeil, a layer of 18k gold over sterling silver, which should never be scrubbed with a silver polishing cloth. More on that in gold vermeil vs gold plated.
How do you stop silver from tarnishing?
You cannot stop it completely, but you can slow it down until it stops being a problem. Five habits do the work.
Wear it often. The friction of daily wear polishes silver constantly. Pieces that live in a drawer tarnish faster than pieces that live on you.
Put it on last. Aftershave, sunscreen, hairspray and moisturiser all react with silver. Dress, do everything else, then put the jewellery on.
Dry it. After swimming, training or washing up, rinse in fresh water and dry it with a soft cloth. Moisture left in a chain or behind a setting is where tarnish starts.
Store it dry and airtight. A zip-lock bag or pouch with the air pressed out slows tarnish more than anything else, because the reaction needs air. An anti-tarnish strip helps. Keep it out of the bathroom.
Keep pieces apart. Silver scratches silver, so store chains separately.

Frequently asked questions
Is tarnish a fault or a defect?
No. Tarnish is a normal reaction between the copper in sterling silver and sulphur in the air, and it happens to all sterling silver eventually. It sits on the surface and cleans off. Our lifetime craftsmanship warranty covers manufacturing defects such as a failed clasp or a loose setting, not tarnish or normal wear.
How often should I clean my silver?
A wipe with a soft cloth after wearing is enough most of the time. Wash a piece properly in warm soapy water every few weeks if you wear it daily, and reach for a polishing cloth only when you can see a grey or yellow film forming.
Why did my silver tarnish so fast when my friend's did not?
Body chemistry. Sweat composition, skin acidity and the products a person uses all change how quickly silver reacts. Climate matters too, since humid coastal air tarnishes silver faster than dry inland air. It says nothing about the quality of the metal.
Does sterling silver rust?
No. Rust is iron oxide and there is no iron in sterling silver. What looks like rust is tarnish, a silver sulphide film caused by the copper in the alloy reacting with sulphur. It sits on the surface and removes cleanly, whereas rust eats into metal.
What is the best way to store silver jewellery?
Dry, airtight and separate. Press the air out of a small zip-lock bag or use an airtight pouch, add an anti-tarnish strip if you have one, and store each piece on its own so nothing scratches or tangles. Keep it out of the bathroom and away from wool and rubber.
Will polishing wear my silver away?
Not in any meaningful way. A jeweller's polishing cloth lifts the tarnish film rather than the metal beneath it, so normal polishing over a lifetime takes off almost nothing. Abrasives are the danger, which is why toothpaste, scourers and repeated harsh dips do real harm.
Can I use a silver dip on an oxidised ring?
No. Chemical dips strip tarnish indiscriminately, and an oxidised finish is intentional tarnish sitting in the recesses of a piece. A dip lifts it and leaves the design flat. Clean oxidised pieces with mild soapy water and wipe only the raised, polished areas.
