Who Are We

Edinburgh Assay Office has tested and hallmarked precious metal items since 1457. We are one of four government-authorised assay offices in the UK and are based at Goldsmiths Hall in the City of Edinburgh.
Today, we have built an international reputation for excellence in our field. This is based on the quality of our hallmarks, the quality of our service, the professionalism of our staff and our ability to develop simple solutions to complex problems.
We exist to safeguard consumers and guarantee the precious metal content of every item that carries our iconic Edinburgh Castle Hallmark.
