How to Tell If Sterling Silver Is Real in the UK
Buying sterling silver jewellery should feel exciting — not uncertain. If you’re shopping in the UK, especially online, it’s important to know how to identify genuine 925 sterling silver and avoid silver-plated or fake alternatives.
This guide explains exactly how to check if silver is real, what UK hallmarks mean, and what to look for before you buy.
1. Check for the 925 Stamp
Real sterling silver contains 92.5% pure silver and 7.5% other metals (usually copper). That’s why genuine pieces are stamped with:
- 925
- .925
- Or a full UK hallmark
However, not all small items are legally required to be hallmarked in the UK. According to the British Hallmarking Council, items under certain weight thresholds (e.g., small earrings or fine rings) may not carry a full hallmark.
So while a 925 stamp is a strong indicator, the absence of one does not automatically mean it isn’t real.
2. Understand UK Hallmarks
In the UK, genuine silver above the legal weight limit must be hallmarked by an official Assay Office such as:
- London Assay Office
- Birmingham Assay Office
- Sheffield Assay Office
- Edinburgh Assay Office
A full UK hallmark usually includes:
- A maker’s mark
- The metal fineness mark (925)
- An assay office symbol
- Sometimes a date letter
If you’re investing in heavier pieces, this hallmark is a strong sign of authenticity.
3. Do the Magnet Test
Silver is not magnetic.
If a strong magnet pulls your jewellery firmly, it likely contains base metals like steel. However:
- Weak attraction may happen due to clasps or internal components.
- This test alone isn’t definitive.
Use it as a quick screening tool — not final proof.
4. Check the Weight and Feel
Sterling silver has a noticeable density and weight compared to plated jewellery. Real silver feels:
- Solid
- Cool to the touch
- Substantial for its size
Silver-plated pieces often feel lighter because the core metal is typically brass or copper.
5. Look for Tarnish (Yes, Really)
Real sterling silver can tarnish over time — especially in the UK’s damp climate.
This is actually a good sign.
Tarnish appears as slight darkening or oxidation and can be polished away easily. Silver-plated jewellery may flake or show a different coloured metal underneath instead.
6. Perform a Polish Test
Gently rub the jewellery with a soft white cloth.
If you see black residue, that’s silver oxide — a natural reaction of real silver with oxygen.
If you see green marks, it may indicate copper from a plated piece reacting with moisture.
7. Buy From Reputable UK Makers
The safest way to ensure authenticity is to buy from:
- Independent UK jewellers
- Sellers who clearly state “solid 925 sterling silver”
- Businesses that provide metal details transparently
Handmade sterling silver jewellery from trusted UK makers offers not only authenticity, but also craftsmanship that mass-produced imports often lack.
