The tool provides an instant way to decode the tiny symbols stamped on antique and vintage jewellery, helping users determine a piece’s gold or platinum purity, assay office location, and hallmark date — all in seconds.
Hallmarks are the official stamps that certify precious-metal items and are essential for authenticating and valuing jewellery. Britain’s hallmarking system, one of the most stringent in the world, dates back to 1300. Yet correctly identifying these marks often requires expert knowledge or time-consuming reference work.
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.”
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.
