What to remember
Caring for a 925 Silver piece of jewellery comes down to two things: slowing down oxidation, and protecting its shape. Silver darkens on contact with air; that is simply its nature. It is also a soft metal, which means it can lose its shape. The gestures that preserve both qualities take only a few seconds each day.

Why 925 Silver Tarnishes
925 Silver contains 92.5% pure silver and 7.5% copper. When exposed to the sulphur present in air, cosmetics and perspiration, its surface transforms into silver sulphide: the grey, then black patina that everyone is familiar with.
Moisture accelerates everything. A ring worn in the shower or a necklace taken into the pool will tarnish two to three times faster than a piece carefully dried after each wear. Chlorine introduces an aggressive element, and perspiration adds another: it is rich in sulphur and mineral salts.
We often hear the same remark: "my jewellery has oxidised, it must be poor quality." Not at all. Silver that never darkened would not be silver.
All silver oxidises, and not only jewellery. Family silverware turns black in a drawer, serving dishes tarnish on a shelf, a christening cup greys within months. No one concludes from this that the silverware is poorly made. It is the same reaction, on the same metal. The darkening of silver is like the patina of leather or the grey of zinc: the mark of a living material, not a failing one.
And it is not inevitable. Silver sulphide is a surface layer: it can be slowed through care and removed through cleaning. The metal beneath remains entirely intact.
The 5 Daily Habits
Five gestures are all it takes, and none of them requires more than ten seconds.
The habit
When
Why
1. Remove before water exposure
Shower, pool, sea, washing up
Moisture, chlorine, and salt accelerate oxidation. This single habit alone can cut cleaning frequency in half.
2. Apply cosmetics first
Perfume, cream, styling gel
These products contain sulphur and acidic agents. Apply them before putting on your jewellery, then wait two to three minutes before getting dressed.
3. Wipe after each wear
Every evening, ten seconds
Sebum and moisture form a film where tarnish takes hold. The polishing cloth included with every order is made exactly for this purpose.
4. Store away from air
Occasionally worn pieces
An anti-tarnish pouch or a closed box limits contact with air. This is unnecessary for a piece worn every day.
5. Remove before exercise
Running, gym, heavy lifting
One hour of perspiration tarnishes as much as a full normal day of wear, and impact can deform the metal.
Storage: Adapting the Method to How Often You Wear It
Jewellery worn every day, hoops, Earrings, a fine ring, a fine necklace. Wipe them each evening, then set them in a open dish or on a tray. If the piece is dry, open air presents no issue: what matters is wiping it down consistently, not sealing it away.
Occasional jewellery, evening necklaces, ceremonial bracelets, rings worn once a month. Wipe them after wearing, then slip them into an anti-tarnish pouch, a treated fabric containing agents that neutralise sulphur, or into an airtight box.
Where to find them: Cookson-CLAL, a specialist retailer in France, carries treated Town Talk pouches in 8.5 x 8.5 cm and 11 x 11 cm sizes, anti-tarnish sachets measuring 10 x 10 cm sold in packs of ten, and strips designed to be placed inside a closed box. They are also available on Amazon and Etsy. One rule applies without exception: never store a piece of jewellery while it is still damp; an airtight pouch then becomes an incubator for oxidation.
Caring for Silver Set with Precious Stones
Our silver jewellery is set with Emeralds, Sapphires, Rubies, tsavorites and Diamonds. Caring for the metal must never come at the expense of the stone, and the methods found everywhere are designed for bare metal, not a set stone.
Emerald is the most delicate: naturally rich in inclusions, and most often oiled. Never ultrasonic cleaning, never hot water, never prolonged soaking. Heat and baths cause the oil to migrate and reveal fractures. Sapphire and Ruby are corundum, far harder by nature: it is not scratching that threatens them, but impact. A knock against a prong shifts it, and the stone will eventually move.

One rule above all others: a set piece of jewellery is never submerged. Not in a bicarbonate and aluminium bath, not in vinegar, not in an ultrasonic tank. These methods are made for bare metal and they attack what holds the stone just as much as the stone itself.
The right technique, step by step. Fill a bowl with lukewarm water and a single drop of gentle soap. Dip a very soft-bristled toothbrush into the bowl, never the jewellery itself. Brush the metal and the area around the stone without pressing on the prongs. Rinse under a gentle stream of lukewarm water, over a bowl, never over an open sink. Pat dry with a soft cloth, then leave to air for one hour: any water retained beneath the setting must be allowed to evaporate. Finish with a polishing cloth, on the silver parts only, carefully avoiding the stone.
Silver Is a Soft Metal: Protecting the Shape Matters Too
At 92.5% pure silver, this is a soft metal. It scratches, but more importantly, it bends out of shape. A fine ring loses its roundness, a chain twists, a link opens, a prong shifts and the stone is lost.
The gestures that prevent this are the same as those that prevent oxidation, which is convenient: avoid sleeping in your jewellery, remove rings and bracelets before sport and before carrying heavy loads (groceries, luggage, weights), and avoid stacking rings that constantly rub against one another.

Two additional habits to adopt. Never remove a ring by pulling on the stone or the setting: this is the gesture most likely to cause deformation. Always grip the band instead. Store pieces flat, without stacking, so that nothing presses against another. A prong check once a year is all it takes to catch a shifting setting before it gives way.
Common Mistakes
Cleaning with toothpaste is a persistent myth. Toothpaste contains micro-abrasives (silica, calcium carbonate) that scratch silver. These scratches create tiny recesses where tarnish takes hold more quickly.
Keeping jewellery on in the shower, even with soft water, is equally inadvisable. Prolonged moisture and soap residue accelerate oxidation, and soap accumulates beneath settings.
Storing jewellery while still damp, after rain or washing your hands, should always be avoided. Dry each piece thoroughly before putting it away, without exception.
A Silver Piece Can Always Be Restored
This is the good news, and it applies to every piece: a silver jewel is never truly lost. Even blackened, even forgotten for ten years in a drawer, the metal beneath the patina remains intact.
What changes is the effort required. A piece wiped down each evening takes two minutes to restore. A piece where oxidation has set in over years calls for a lengthy cleaning process, often repeated, sometimes requiring the attention of a professional. The more consistent the care, the easier it is to keep the piece looking its best.
As little as possible. 925 Silver does not rust, as it contains no iron, but moisture accelerates the reaction between silver and the sulphur found in the air and on the skin. Removing your jewellery before showering, swimming, or going in the sea will cut the frequency of cleaning in half. If your piece does get wet, dry it immediately with a soft cloth.
My silver jewellery has oxidised. Is this a sign of poor quality?
No. Oxidation is the very nature of silver: all silver darkens when exposed to sulphur in the air, whether jewellery, cutlery, or serving pieces. A metal that never tarnishes is simply not silver. Tarnish is a surface layer only; it can be completely removed, leaving the metal beneath perfectly intact.
How do you restore the shine of 925 Silver?
When a daily wipe-down is no longer enough, a deeper clean becomes necessary. This is a subject in its own right, which we cover method by method in our dedicated guide. One essential point to keep in mind before you begin: soaking baths are for bare metal only, never for jewellery set with stones.
Can you clean a silver jewellery piece set with Emerald or Sapphire?
Yes, but never by soaking. No ultrasonic cleaners, no hot water, no bicarbonate baths or vinegar: emeralds are treated with oil, and heat causes that oil to migrate. The right approach is lukewarm water, a gentle soap, a very soft brush, a thorough rinse and complete drying, followed by a polish with a polishing cloth on the metal, carefully avoiding the stone.
Can you slow down the oxidation of 925 Silver?
Yes, quite noticeably. Remove your jewellery before contact with water, apply cosmetics before putting it on, wipe it gently after each wear, and store it away from air when worn only occasionally: a well-maintained piece tarnishes two to three times more slowly than one left without care. These habits take only a few seconds each day.
Does white vinegar damage silver?
Not on bare silver: diluted white vinegar is a mild acid that dissolves silver sulfide without attacking the metal itself. What it does damage is everything else. On a set stone, it seeps beneath the gem, gradually dulls the prongs, and can draw the oil out of an emerald. On a piece with intentional oxidation (a darkened motif designed for contrast), it strips away the desired patina. A simple rule: vinegar on bare metal only, never on a set stone.
Can you wear a 925 Silver piece every day?
Yes, and it is actually the best way to keep it bright. A worn piece rubs gently against skin and fabric, which maintains the polish and slows sulphide build-up; a piece left forgotten in a drawer tarnishes faster. Two caveats, though: remove it before water, sport, and sleep, and remember that silver is a soft metal, so daily wear gradually affects the shape as well as the shine.
Where can you find an anti-tarnish pouch?
Specialist jewellery suppliers such as Cookson-CLAL carry Town Talk anti-tarnish pouches in 8.5 x 8.5 cm and 11 x 11 cm sizes, anti-tarnish bags measuring 10 x 10 cm sold in packs of 10, and strips designed to be placed inside a closed box. These products are also available on Amazon and Etsy. The treated felt works by neutralising the sulphur present in the air inside the pouch.
Conclusion
Caring for your 925 Silver jewellery does not eliminate the need for occasional cleaning; it simply reduces how often that cleaning is needed, while protecting the piece beyond oxidation alone. Wiping it down each evening, removing it before contact with water or sport, applying cosmetics first, storing it away from air, and never pulling on a stone: these simple habits preserve both the brilliance and the shape of your silver jewellery.
