Why does sterling silver tarnish? If you’ve ever noticed your jewellery turning darker over time, don’t worry – this is completely normal. Tarnish is a natural chemical reaction, not a sign of poor quality.
This guide explains what causes tarnish, why some people experience it more than others, and how to slow it down.
What is tarnish?
Tarnish is a thin dark layer that forms on the surface of silver when it reacts with sulphur compounds in the air. This process is called oxidation.
It does not damage the silver – it simply changes the surface colour.
Why does sterling silver tarnish faster than pure silver?
Sterling silver contains 92.5% silver and 7.5% other metals, usually copper. These added metals strengthen jewellery but also react more easily with air and moisture.
This is why sterling silver tarnishes faster than fine silver (999).
Main causes of silver tarnish
- Humidity and damp air
- Perfume and hairspray
- Sweat and skin oils
- Household cleaning chemicals
- Pollution
Why does silver tarnish more on some people?
Body chemistry varies from person to person. Factors include:
- Skin pH levels
- Medication
- Diet
- Hormonal changes
This is why two people can wear the same ring and have different tarnish results.
Does wearing silver prevent tarnish?
Yes – regular wear can actually slow tarnish. Natural skin oils help protect the surface. However, remove jewellery before:
- Showering
- Swimming
- Cleaning
How to slow down tarnishing
Store jewellery correctly
- Airtight bags
- Anti-tarnish strips
- Dry storage away from bathrooms
Clean regularly
Gentle cleaning every few weeks prevents heavy buildup.
Avoid chemicals
Perfume and cleaning sprays accelerate tarnish.
Is tarnish permanent?
No. Tarnish sits on the surface and can be removed safely with proper cleaning.
Common myths
“Real silver doesn’t tarnish.”
False. All sterling silver tarnishes eventually.
“Tarnish means low quality.”
No – even high-quality silver tarnishes.
“Black silver is ruined.”
Not at all. It just needs cleaning.
FAQ
Does gold-plated silver tarnish?
