Using state-of-the-art non-contact laser hallmarking equipment, provided by Edinburgh Assay Office, we provide British hallmarking and convention marks for silver, gold, jewellery and precious metals. And because we do this on-site at our own facilities, our hallmarking is more efficient which ensures faster turnaround times for clients who are kept informed at every step of the assay service.
In the UK, and most other European markets, items of gold, silver, platinum, and palladium (over a certain weight threshold) must undergo testing to determine its precious metal content and quality – know as assay – and hallmarking by a government-authorised assay office as a pre-market authorisation.
British Hallmarks, stamped by a UK assay office, verify that an alloy’s precious metal content meets national and international standards of purity and fineness. It is illegal to offer such items for sale without a recognised hallmark.

The FAQs below relate to our laser hallmarking service. Should the answer you require not be listed, please do not hesitate to contact us.
Under the UK Hallmarking Act of 1973, all items made of precious metals (gold, silver, platinum, and palladium) above certain weight thresholds must be hallmarked. Without a hallmark, it is illegal to describe or sell the item as a precious metal. Many other European countries require a hallmark too. Our in-house hallmarking facility can apply UK hallmarks and internationally recognised common control marks.
Items below these weights do not need to be hallmarked.
A hallmark guarantees that the metal used in the item meets the standards for purity and authenticity set by UK law. It prevents consumers from unknowingly purchasing counterfeit or substandard items.
If the precious metal item exceeds the weight threshold and is not hallmarked, it is illegal to sell it as gold, silver, platinum, or palladium in the UK. Non-hallmarked items cannot be advertised or sold. If you have a retail unit and are selling precious metal items, you must display a Section 11 Dealer’s Notice. The Dealer’s Notice can be found here.
Selling non-hallmarked items as precious metals is against the law in the UK. You could face fines or legal action, and your reputation as a jeweller could be damaged.
At Ferrari Express Ltd, sustainability is at the core of our hallmarking process. Traditionally, hallmarking involved transporting items to off-site facilities, leading to longer supply chains and increased carbon emissions. By situating our facility directly at Heathrow Airport—where goods arrive from abroad—we eliminate the need for additional transportation. This not only shortens the supply chain but also reduces our carbon footprint.

This streamlined process helps us provide a faster, more eco-friendly service while contributing to a greener future.
