What is Hallmarking? Understanding UK Gold & Silver Hallmarks on Memorial Jewellery
Share
If you've ever purchased gold or silver jewellery in the UK, you've likely noticed tiny symbols stamped on the metal. These are hallmarks, and they're your guarantee that your precious metal jewellery is genuine. When investing in memorial jewellery to preserve ashes, hair, or flowers, understanding hallmarks is essential - including when they're required and when they're not.

What is a Hallmark?
A hallmark is an official mark stamped onto gold, silver, platinum, or palladium items to certify their precious metal content. In the UK, hallmarking has been a legal requirement for over 700 years, making it one of the oldest forms of consumer protection in the world.
When you purchase hallmarked jewellery, you're guaranteed that the metal content is exactly what the seller claims. However, it's important to understand that not all precious metal jewellery requires hallmarking - and that's completely legal and normal.
Is Hallmarking Required on All Jewellery?
In the UK, hallmarking is legally required on all gold, silver, platinum, and palladium items that weigh above certain thresholds:
- Gold: Items over 1 gram must be hallmarked
- Silver: Items over 7.78 grams must be hallmarked
- Platinum: Items over 0.5 grams must be hallmarked
- Palladium: Items over 1 gram must be hallmarked
This means that many delicate memorial pieces are exempt from hallmarking requirements:
- Small sterling silver earrings and pendants (under 7.78 grams)
- Delicate 9ct gold earrings and small pendants (under 1 gram)
- Thin sterling silver rings and stacking bands (under 7.78 grams)
However, larger pieces will be hallmarked:
- 9ct gold rings (most are over 1 gram and therefore hallmarked)
- 9ct gold chains (typically over 1 gram)
- Heavier 9ct gold pendants (over 1 gram)
- Any 9ct gold piece over 1 gram
- Heavier sterling silver pieces (over 7.78 grams)
If your memorial jewellery is below these weight thresholds, it's perfectly legal and normal for it not to have a hallmark. This doesn't mean the metal isn't genuine - it simply means the piece is too small to require hallmarking by law.
Understanding UK Hallmark Symbols
When jewellery does have hallmarks, a complete UK hallmark typically consists of four symbols:
1. The Sponsor's Mark (Maker's Mark)
This identifies the jeweller or company responsible for sending the item for hallmarking. This is typically the manufacturer who created the original metal component.
2. The Fineness Mark (Purity)
This indicates the precious metal content:
- 9ct Gold: 375 (37.5% pure gold)
- 18ct Gold: 750 (75% pure gold)
- 22ct Gold: 916 (91.6% pure gold)
- Sterling Silver: 925 (92.5% pure silver)
- Britannia Silver: 958 (95.8% pure silver)
For memorial jewellery, 9ct gold and sterling silver are the most popular choices, offering an excellent balance of durability, beauty, and value.

3. The Assay Office Mark
This shows which UK Assay Office tested and hallmarked the item. There are four Assay Offices in the UK:
- London: Leopard's head
- Birmingham: Anchor
- Sheffield: Rose (or Yorkshire Rose)
- Edinburgh: Castle
4. The Date Letter (Optional)
This letter indicates the year the item was hallmarked. While optional, many manufacturers include it to provide a complete record of the piece's origin.

Why Hallmarks Matter for Memorial Jewellery
Memorial jewellery holds deep sentimental value. Whether you're preserving ashes from a loved one, pet fur from your dog or cat, or flowers from your wedding bouquet, you want to ensure your keepsake is made from genuine precious metals that will last a lifetime.
When hallmarks are present, they provide:
- Authenticity: Proof that your gold or silver is genuine
- Quality Assurance: Independent verification by a UK Assay Office
- Investment Protection: Hallmarked items retain their value better
- Heirloom Quality: Precious metals that will last for generations
- Peace of Mind: Confidence that you're getting what you paid for
However, the absence of a hallmark on a small, delicate piece doesn't mean it's not genuine precious metal - it simply means it's below the legal weight threshold for hallmarking.
What About Gold-Filled Jewellery?
Gold-filled jewellery is not hallmarked because it's not solid gold. Instead, it consists of a thick layer of gold bonded to a base metal core. While gold-filled pieces offer an affordable alternative to solid gold and are much more durable than gold-plated items, they don't meet the legal definition of "gold" for hallmarking purposes.
At Lovely Oxford, we clearly label all our gold-filled memorial jewellery so you know exactly what you're purchasing. Gold-filled pieces are an excellent choice for memorial jewellery if you want the look of gold at a more accessible price point.
Hallmarking at Lovely Oxford
At Lovely Oxford, I create delicate, handcrafted memorial jewellery in my South Oxfordshire studio. Here's what you can expect regarding hallmarks on different types of pieces:
9ct Gold Pieces Over 1 Gram (Hallmarked):
- 9ct gold rings - hallmarked on the inside of the band
- 9ct gold chains - hallmarked near the clasp
- Heavier 9ct gold pendants - hallmarked on the back or bail
- Any 9ct gold piece over 1 gram will be hallmarked
9ct Gold Pieces Under 1 Gram (Not Hallmarked):
- Delicate 9ct gold pendants
- Small 9ct gold earrings
- Lightweight 9ct gold charms
Sterling Silver Pieces (Typically Not Hallmarked):
- Most sterling silver memorial pieces (earrings, pendants, rings) weigh less than 7.78 grams
- This is completely legal and normal for delicate jewellery
What This Means for You:
When you purchase memorial jewellery from Lovely Oxford, whether your piece is hallmarked depends entirely on its weight. All pieces are made from genuine precious metals - the hallmark simply indicates that the piece is heavy enough to require legal certification.
How to Verify Your Memorial Jewellery is Genuine
If your memorial jewellery doesn't have a hallmark because it's below the legal weight threshold, how can you be sure it's genuine precious metal?
- Buy from reputable jewellers who are transparent about their materials
- Ask for documentation about the metal content
- Check for hallmarks on heavier pieces like rings and chains
- Look for quality craftsmanship and attention to detail
- Read reviews from other customers
At Lovely Oxford, I'm completely transparent about the materials I use. All my sterling silver is genuine 925 sterling silver, and all my 9ct gold is genuine 375 gold, whether or not the piece is large enough to require hallmarking.
How to Check Hallmarks on Your Memorial Jewellery
If your memorial jewellery does have hallmarks, they're typically stamped on:
- Rings: Inside the band
- Chains: Near the clasp or on a small tag
- Pendants: On the back or near the bail (if over 1 gram)
- Bracelets: Near the clasp
- Earrings: On the back of posts or hooks (if large enough)
Hallmarks are small, so you may need a magnifying glass or jeweller's loupe to read them clearly. Look for the fineness mark (375 for 9ct gold, 925 for sterling silver) along with the Assay Office symbol and manufacturer's mark.
Caring for Your Memorial Jewellery
Whether hallmarked or not, precious metal jewellery is designed to last a lifetime with proper care:
- Remove before swimming or showering to prevent tarnishing
- Store in a dry place away from moisture
- Clean gently with a soft cloth
- Avoid harsh chemicals and abrasive cleaners
- Have it professionally cleaned if needed
Choosing Quality Memorial Jewellery
When selecting memorial jewellery to preserve ashes, hair, pet fur, or flowers, focus on:
- Reputable jewellers who are transparent about materials
- Quality craftsmanship and attention to detail
- Genuine precious metals (even if below hallmarking thresholds)
- Clear communication about what to expect
- Customer reviews and testimonials
At Lovely Oxford, all my memorial jewellery uses genuine precious metals - sterling silver, 9ct gold, or gold-filled - regardless of whether the piece is large enough to require hallmarking. I'm committed to transparency and quality in every piece I create.
Frequently Asked Questions About Hallmarks
Is my jewellery fake if it doesn't have a hallmark?
No! If your jewellery is below the legal weight threshold, it doesn't require a hallmark. Many delicate memorial pieces are too small to require hallmarking, but they're still made from genuine precious metals.
Why does my chain have a hallmark but my pendant doesn't?
Chains are often heavier than pendants and exceed the legal weight threshold for hallmarking. It's completely normal for a chain to be hallmarked while a small, delicate pendant is not.
Will my 9ct gold ring be hallmarked?
Yes! Most 9ct gold rings weigh over 1 gram and are therefore hallmarked. You'll find the hallmark stamped on the inside of the ring band.
Will my 9ct gold pendant be hallmarked?
It depends on the weight. Heavier pendants over 1 gram will be hallmarked, while delicate pendants under 1 gram won't be. Both are made from genuine 9ct gold.
Can hallmarks wear off over time?
Hallmarks are stamped into the metal, so they're permanent. However, they may become less visible with wear, especially on rings. This doesn't affect the metal's authenticity.
Do all countries use the same hallmarking system?
No, hallmarking systems vary by country. The UK has one of the oldest and most rigorous systems in the world.
Are there penalties for selling unhallmarked items that should be hallmarked?
Yes, selling precious metal items above the legal weight threshold without proper hallmarks is a criminal offence in the UK. However, selling items below the threshold without hallmarks is perfectly legal.
