Assay Office Birmingham has seen a big increase in sales of both its AnchorCert Gem Weight Estimator app and Help with Hallmarks app.

AnchorCert Gemstone Weight Estimator App

Gemmologists and Valuers from around the world have praised the app, informing staff who attended the recent Gemmological Association of Great Britain's Conference that they found the Apps very useful for calculating an estimated carat weight of a diamond or gemstone and for dating pieces of jewellery and silverware.


If you would like to purchase the AnchorCert Gem Weight Estimator app, you can do so by downloading it from the Google Play Store and the Apple App Store for a price of £14.99.

The Help with Hallmarks app also experienced a high level of downloads and is especially useful for valuer, retailers, pawnbrokers and auctioneers. The app enables users to quickly research and identify the date letter on precious metal, jewellery and silverware. The app includes date letters from the eleven key assay offices in the UK, going back as far as 1544.

Hallmarking App

The app contains useful information relating to hallmarks, and is an invaluable “on the go” tool for retailers, collectors, antique and second hand dealers, silver experts, valuers and students, as well as members of the public who have a general interest in historic hallmarks.
