Common Myths About Sterling Silver
What Is Sterling Silver?
Sterling silver is a precious metal alloy made up of 92.5% pure silver and 7.5% other metals (usually copper).
Pure silver (99.9%), often referred to as “fine silver”, is too soft for jewellery. It can bend, dent, or scratch easily. The addition of a small amount of another metal gives the silver structural strength without significantly changing its colour or shine.That’s why sterling silver is the global jewellery standard.
Key takeaway:
Sterling silver keeps silver’s beauty but adds the durability needed for rings, chains, bangles, earrings, and everyday items, something pure silver can’t offer.
What Does 925 Mean?
When you see a piece stamped with “925”, that means:
- The metal contains 92.5% silver
- The rest (7.5%) is alloy metal, usually copper
- The stamp is the international standard for sterling silver authenticity
This is why “925”, “.925”, and “92.5%” are all used interchangeably.
Legally in many regions (including EU, UK, and common jewellery markets), a piece must meet this percentage to be labelled “sterling silver.”
Is Sterling Silver Real Silver?
Yes. Sterling silver is real silver.
It is not silver-plated or imitation metal. While it isn’t 100% pure, the 92.5% silver content qualifies it as fine jewellery metal.
People sometimes get confused because:
- Pure silver (999/1000) is different from sterling silver (925/1000).
Some sellers misuse 925 marks without real silver underneath. Always verify authenticity.
Is Sterling Silver Pure Silver?
Not exactly.
Sterling silver is not 100% pure silver. It’s a blend with metals that make it stronger. That 7.5% alloy addition is essential for jewellery use. Without it, silver jewellery would be fragile and unsuitable for daily wear.
Sterling Silver vs. Pure Silver — What’s the Difference?
Here’s a deeper comparison:
Sterling silver hits the sweet spot between value, shine, and usability. For jewellery, sterling silver is the better option.
Pros and Cons of Sterling Silver
Pros
- Real precious metal
- Durable for everyday use
- Affordable compared to gold
- Easy to polish
- Retains scrap value
- Suitable for gifting
Cons
- Can tarnish over time
- Requires occasional cleaning
- Softer than platinum or gold
Does Sterling Silver Tarnish?
Yes. But not excessively.
All silver, including sterling silver, reacts with air, moisture, sweat, and sulphur compounds, which may cause a tarnish layer (a dull or slightly dark film). This is normal and not a sign of fake jewellery.
Tarnish tips:
- Regular wear can slow tarnishing (skin oils can protect metal).
- Proper storage (air-tight pouch) reduces exposure.
- Simple cleaning keeps it bright.
How to Clean & Maintain Sterling Silver
Your jewellery deserves care. Here is a simple routine to care for your sterling silver jewellery.
- Daily: Soft polishing cloth (avoid rough scrubbing).
- Weekly: Mild soap + lukewarm water, dry immediately.
- Occasional: Baking soda paste applied gently.
What to Avoid
- Abrasive cleaners
- Toothpaste or baking soda applied aggressively
- Swimming with jewellery (chlorine accelerates tarnish)
With consistent care, even older pieces can look new again.
How Much Is 925 Sterling Silver Worth?
Unlike gold or diamonds, sterling silver’s market value is based mainly on the metal price per gram, not rarity. Sterling silver’s worth depends on:
- Current silver rate
- Weight of the piece
- Craftsmanship & design
- Brand & retail markup
Pure melt value (metal alone) does not decide jewellery value. Design and labour efforts are also considered.
How to Spot Fake Sterling Silver
Not every piece stamped “925” is real. Some scams exist. Here’s how to verify:
Check the Hallmark: Genuine pieces have clear, crisp hallmarks.
Magnet Test: Silver is not magnetic. If it sticks strongly to a magnet, it’s not sterling silver.
Density Feel: Cheap plated metal feels unnaturally light for its size.
Professional Testing: Acid testing or XRF testing by a jeweller confirms authenticity.
Hallmarking & Legal Standards for Sterling Silver
Hallmarking protects buyers from fraud and confirms metal purity through regulated testing.
🇮🇳 India — BIS Hallmarking (Bureau of Indian Standards)
In India, silver jewellery can be certified under Bureau of Indian Standards (BIS).
A valid BIS hallmark typically includes:
- BIS logo
- Purity mark (925 for sterling silver)
- Assay centre identification
- Jeweller’s identification mark
Official reference: BIS Hallmarking Guidelines — https://www.bis.gov.in
BIS certification ensures the silver meets declared purity standards under Indian law.
🇬🇧 United Kingdom — Assay Office System
In the UK, sterling silver is hallmarked by authorised assay offices such as:
- Assay Office London
- Assay Office Birmingham
Under the UK Hallmarking Act, precious metals must be independently tested and stamped before sale.
Official reference: UK Hallmarking Act Guidance — https://www.assayofficelondon.co.uk
A UK hallmark includes:
- Sponsor’s mark
- Fineness mark (925 for sterling silver)
- Assay office mark
- Optional date letter
🇪🇺 European Standard
In the European Union, sterling silver must meet 925/1000 fineness standards to be legally described as “sterling silver.”
Reference: European Convention on the Control and Marking of Articles of Precious Metals (Common Control Mark – CCM)
Official information: https://www.hallmarkingconvention.org
Is Sterling Silver Hypoallergenic?
Generally yes. But here are a few things to check.
Sterling silver is often skin-friendly, especially when alloyed with copper and not nickel. If a piece includes nickel or cheap alloys, irritation may occur. So confirm metal composition on sensitive skin products.
