Help with Hallmarks allows users to quickly identify metal marks.

The Birmingham Assay Office (BAO) has created a new app called Help with Hallmarks, suited to iPhone, iPad and Android devices.

The app allows users to quickly research and identify date letters on jewellery or items of silverware, and has been preloaded with all date letters from the 11 UK assay offices dating back to 1544.


It has a price tag of £9.99 and is designed for jewellers and retailers "on the go", as well as collectors, antique and second hand dealers, silver experts, valuers and students.

The Help with Hallmarks app follows on from the AnchorCert Gemstone Weight Estimator app which has been available for a number of years and has been sold worldwide on both Apple and Android platforms.

The Gemstone Estimator app allows users to easily calculate the estimated carat weight of diamonds and gemstones from their measurements. The calculation will use the measurement of the length, width and depth of the gemstone (and the minimum and maximum diameter of round brilliant diamonds.)
