What Is Sterling Silver Jewellery?
Sterling silver jewellery is made from 92.5% pure silver, mixed with 7.5% copper. You might see it stamped as “925”. That touch of copper makes the silver strong enough for rings, chains, and studs you can wear every day, but it’s also what makes it susceptible to tarnish.
Why Does Sterling Silver Jewellery Tarnish?
Tarnish is a surface reaction. When sterling silver jewellery comes into contact with sulphur-containing substances in the air (and on our skin), it forms a layer of silver sulphide—that dark discolouration you see. It’s especially common in humid areas or near the coast.
Common causes of tarnish:
- Air and humidity: Especially in coastal or urban areas
- Skin chemistry: Sweat, oils, and individual pH levels can speed it up
- Lotions and sprays: Perfume, hairspray, sunscreen, and hand cream
- Storage: Leaving jewellery exposed to air when it’s not being worn
- Chemicals in water: Chlorine in pools and spa baths can significantly speed up tarnishing, sometimes even causing pitting or irreversible surface damage if exposure is prolonged.
So yes, real sterling silver jewellery can tarnish. It’s a normal chemical reaction, not a sign of poor quality.
How to Keep Sterling Silver Jewellery From Tarnishing
You can’t stop tarnish completely, but you can slow it down significantly:
- Store it smart: Keep your pieces in an airtight pouch or ziplock bag. Anti-tarnish strips or cloths help too.
- Wear it often: The natural oils in your skin can actually help keep silver polished.
- Avoid water and chemicals: Remove your jewellery before swimming, showering, or applying skincare products.
- Dry it thoroughly: Moisture accelerates tarnish. Always dry your jewellery before storing it.
How to Clean Tarnished Sterling Silver Jewellery at Home
If your jewellery has already tarnished, don’t stress. It’s easy to fix.
Effective cleaning methods:
- Silver polishing cloth: Great for light tarnish and regular maintenance.
- Foil method: Line a bowl with aluminium foil, add hot water and a tablespoon of baking soda. Let your jewellery sit for a few minutes, then rinse and dry. Ideal for more stubborn tarnish.
- Liquid silver cleaner: Commercial silver dips can be effective, but use them sparingly. Avoid prolonged exposure and always follow the product instructions carefully.
Avoid using toothpaste. It can be too abrasive and cause tiny scratches over time.
Can I Wear It Every Day?
You can wear sterling silver jewellery every day. In fact, frequent wear helps reduce tarnish. Just avoid prolonged exposure to water and store it properly when you take it off.
Real sterling silver reacts. That’s part of its nature. But with a little knowledge and care, it stays just as beautiful as the day you got it.

FAQs
Does real sterling silver tarnish?
Yes, it does. Tarnish is a natural surface reaction when sterling silver interacts with sulphur-containing substances in the air or on skin. It doesn’t mean the piece is fake or poor quality.
How can I clean tarnished silver at home?
Use a silver polishing cloth for light tarnish. For deeper cleaning, try the foil method: line a bowl with aluminium foil, add hot water and baking soda, soak your jewellery for a few minutes, rinse, and dry.
What causes silver to turn black or yellow?
The main culprits are air pollutants, humidity, skin oils, lotions, perfumes, and exposure to water—especially chlorinated water. These elements react with the copper in sterling silver.
Is tarnish a sign of fake jewellery?
Not at all. Tarnish is actually a sign that your silver is real. It’s caused by a natural reaction with elements in the environment, not a defect or indication of fakeness.
Can I wear sterling silver every day?
Yes! In fact, daily wear can help prevent tarnish because the natural oils from your skin polish the silver over time. Just avoid contact with water and chemicals and store it properly.
What type of silver doesn’t tarnish?
Pure silver (99.9%) tarnishes less but is too soft for jewellery. Sterling silver (92.5%) is stronger but more reactive. Plated or coated silver may resist tarnish temporarily but will degrade over time. There’s no silver that never tarnishes—but some tarnish more slowly than others.
Why does some silver tarnish faster than others?
It depends on factors like humidity, pollution, exposure to products, and even your skin’s pH. For example, sweat with a lower pH or oily skin can accelerate tarnishing.
How long does 925 silver last?
With proper care, 925 sterling silver can last a lifetime. Tarnish is only surface-level and can be cleaned, while the metal underneath remains strong and durable.
