We're so much more than hallmarking

welcome to assay office birmingham

Assay Office Birmingham was founded in 1773 to provide assaying (testing) and hallmarking  of precious metal items (gold, silver, platinum and palladium) as required by the Hallmarking Act.

It has been a centre of expert opinion and independent assessment of jewellery and precious metals for nearly 250 years.

During recent decades it has expanded its services far beyond its statutory assaying and hallmarking duties to include Diamond, Gemstone & Pearl Certification, Jewellery, Watch and Silverware Valuations, non precious metal testing, product safety and quality assurance testing as well as educational training and consultancy.
