Antique Jewellers Ltd, a renowned UK antique ring retailer, has launched a complimentary Hallmark Finder — a digital tool tailored to support enthusiasts and professionals alike in identifying British jewellery hallmarks with ease.
The tool decodes hallmark symbols found on older jewellery items, instantly providing details about metal purity (gold or platinum), the assay office of origin, and the approximate hallmark date. It streamlines a process that previously relied heavily on expert input or manual reference guides.
As official stamps that validate the precious metal content, hallmarks are central to both valuing and verifying jewellery. The UK’s hallmarking tradition, one of the most regulated in the world, stretches back over 700 years, but correct identification can still be time-intensive without the right resources.
“Decoding those symbols used to mean laboriously consulting hallmark reference books or charts,” says Drew, Managing Director of Antique Jewellers. “We wanted to create a quick, accessible solution for everyone — whether you’re verifying a family heirloom or cataloguing stock for an auction.”
The tool then explains each hallmark — such as identifying a “375” stamp as 9-carat gold or an anchor symbol as the Birmingham Assay Office. It draws on over 300 years of verified UK hallmark records, covering all major symbols and date letters. Even if a user isn’t sure about a specific symbol or letter, the tool provides an intuitive way to browse possibilities, making it easy to use even for beginners.
“There are other hallmark databases out there, but ours is designed to be extremely user-centric,” Drew adds. “We’ve digitised hallmark charts and built an interactive guide so you don’t need to be an expert to get an answer. And unlike some services, it’s completely free.”
Collectors and professionals are already praising the tool for its speed, ease, and accuracy. Being able to verify a hallmark instantly — whether at an antiques fair or during an appraisal — saves time and helps avoid costly mistakes in evaluating authenticity or value. For example, a dealer can enter a ring’s hallmark into their phone and immediately confirm if it’s 15-carat gold assayed in Chester — something that would otherwise take considerable time to check.
The tool’s results are backed by verified data from UK assay offices and hallmarking history. Its database was built from official charts and historical references, ensuring alignment with established standards.
The company also plans to keep the tool updated as hallmarking standards evolve, ensuring it remains a go-to digital reference for years to come.
