Jewellery Without Hallmarks: What You’re Risking as a Buyer

When buying fine jewellery, most people focus on how a piece looks. Colour, sparkle, design, and price tend to dominate decision-making. What is often overlooked is something far less visible, yet far more important.

The hallmark.

Jewellery without hallmarks may look identical to hallmarked jewellery at first glance, but the absence of a hallmark introduces real risks for buyers. These risks are not about aesthetics. They are about metal purity, value, accountability, and long-term trust.

This guide explains what hallmarks are, why they matter, what you are risking when jewellery is unhallmarked, and how to protect yourself as a buyer.

What Is a Hallmark in Jewellery?

A hallmark is an official mark applied to precious metal jewellery that confirms its metal content.

In practical terms, a hallmark tells you:

• what the jewellery is made of

• the purity of the metal

• who is responsible for placing that metal into the market

Hallmarks are not decorative. They exist to protect buyers.

In many countries, including the UK and parts of Europe, hallmarking is legally regulated. In others, including New Zealand, consumer protection laws still apply, even if hallmarking itself is not mandatory.

Why Jewellery Without Hallmarks Is a Red Flag

Jewellery without a hallmark is not automatically fake, but it removes a layer of protection for the buyer.

When jewellery is unhallmarked, you lose:

• independent confirmation of metal purity

• traceability to a maker or business

• a clear reference point for valuation, resale, or insurance

In short, you are relying entirely on trust without verification.

The Three Biggest Risks of Jewellery Without Hallmarks

1. Metal Purity Risk

Without a hallmark, there is no visible confirmation that a piece is actually made of the metal it is claimed to be.

A ring described as “gold” may:

• be a lower karat than stated

• be heavily alloyed beyond expectations

• contain fillers or mixed metals

For high-value jewellery, this uncertainty matters.

2. Resale and Insurance Risk

Jewellery that cannot be easily verified is harder to:

• insure accurately

• resell or trade

• pass down with confidence

Insurers, valuers, and future buyers rely on hallmarks as a first point of reference. Jewellery without hallmarks often requires additional testing, which adds cost and uncertainty.

3. Accountability Risk

Hallmarks usually include a maker’s mark.

When jewellery is unhallmarked:

• there is no clear accountability

• responsibility is harder to trace

• quality claims are harder to enforce

This matters if issues arise years later.

Gold and Platinum: Why Hallmarks Matter Even More

For gold and platinum jewellery, hallmarks are especially important because visual inspection alone cannot confirm purity.

At Layaz, jewellery is made using:

• 14K gold (585)

• 18K gold (750)

• Platinum PT950

These fineness standards matter not just for value, but for durability, wearability, and long-term performance.

Without a hallmark, buyers have no visible confirmation that these standards are being met.

What Jewellery Hallmarks Usually Look Like

While hallmark formats vary by country, most legitimate hallmarks include some combination of:

• a fineness mark (such as 750, 585, or PT950)

• a maker’s mark identifying who made or placed the jewellery

• sometimes an assay or control mark

Hallmarks are usually found:

• inside ring bands

• on pendant bails

• near clasps on bracelets and chains

They are often small and discreet, but intentional.

Jewellery Without Hallmarks in New Zealand

In New Zealand, hallmarking itself is not legally required in the same way it is in the UK. However, consumer protection laws still apply.

Under the Consumer Guarantees Act and Fair Trading Act:

• jewellery must not be misleadingly described

• metal claims must be accurate

• buyers have the right to truthful information

This means that even without a legal hallmarking system, sellers are still responsible for honesty and transparency.

Why International Standards Still Matter

Just because hallmarking is not mandatory locally does not mean standards should be ignored.

Many reputable jewellers in New Zealand align with international hallmarking and quality standards to provide buyers with greater confidence.

This is where transparency becomes a choice, not an obligation.

How Layaz Approaches Hallmarks and Quality Assurance

At Layaz, hallmarks are treated as one layer of trust, not the only one.

Jewellery produced by Layaz includes:

• appropriate fineness marks for gold or platinum

• a LYZ maker’s mark

• documentation and staged approvals throughout production

Beyond hallmarks, Layaz’s quality assurance includes:

• in-house design and manufacturing

• gemstone verification

• metal accountability at every stage

• final approval before and after delivery

This layered approach ensures buyers are not relying on a single stamp alone.

How to Check If Jewellery Is Hallmarked

If you are buying jewellery, especially at higher price points, it is reasonable to check for hallmarks.

Start by:

• inspecting inside bands and clasps

• using a loupe or magnification

• asking the seller to explain the marks

If you cannot find a hallmark, ask direct questions:

• what metal is this exactly?

• what is the purity?

• is there documentation to support this?

A reputable jeweller will answer clearly.

Red Flags When Buying Jewellery Without Hallmarks

Be cautious if:

• metal descriptions are vague

• sellers avoid explaining composition

• prices seem unusually low for the claimed metal

• there is no paperwork for high-value pieces

• the seller discourages independent verification

These are not guarantees of poor quality, but they are signals to slow down.

Case Study: Auckland Buyer and Unverified Gold

An Auckland buyer purchased a ring described as “solid gold” without any hallmarks or documentation.

Years later, when seeking to insure the piece, independent testing revealed the gold content was lower than expected. The value did not match what was originally paid.

The experience highlighted how the absence of verification created long-term issues rather than immediate ones.

Case Study: Christchurch Client Seeking Transparency

A Christchurch-based client approached Layaz after inheriting jewellery with no hallmarks and unclear origins.

Through consultation and redesign, materials were verified, documented, and transformed into a new piece with full transparency. The result restored confidence and preserved sentimental value.

Jewellery Without Hallmarks Does Not Mean You Must Walk Away

Not all unhallmarked jewellery is worthless. Some older pieces predate modern systems, and some bespoke jewellery relies on documentation rather than stamps.

What matters is clarity.

If a seller can explain:

• metal content

• sourcing

• responsibility

and support those claims, the risk is reduced.

Buying Jewellery With Confidence

Hallmarks exist to protect buyers, not to complicate purchasing.

When jewellery is hallmarked, documented, and transparently made, it becomes something you can wear, insure, and pass on with confidence.

That confidence is part of the value.
