Protecting the Consumer and Servicing
the Trade with Independence and Integrity

Company Information



Birmingham Assay Office is a not-for-profit organisation and was founded by An Act of Parliament in 1773.  It has a long established reputation within the jewellery trade as an independent centre of quality assessment and expert opinion.  Millions of gold, silver, platinum and palladium articles arrive here every year to be tested, to ensure that they contain the legal amount of precious metal, prior to being hallmarked. This statutory duty, one of the earliest forms of consumer protection, is still carried out in much the same way it has been for almost 250 years, although the process is now assisted by the latest technology such as X-Ray fluorescence testing and laser marking. 

During  recent times it has expanded its services further, far beyond its statutory assaying and hallmarking duties.  The Organisation is committed to investing in future expansion and in addition to its statutory hallmarking duty, Assay Office Birmingham also continues to develop a significant range of product quality assurance and safety services.

These are all delivered by IN-HOUSE EXPERTS using a wide range of sophisticated equipment. Assay Office Birmingham prides itself on the high level of service provided and the use of the latest technology by all its commercial divisions, from hallmarking, diamond and gemstone certification, jewellery, watch and silverware valuations, through to precious and non precious metal analysis, fashion accessories, leather and textiles testing, as well as educational training and consultancy.
