Every Mark Matters
The Goldsmiths’ Company Assay Office is where hallmarking began, and we have been testing and hallmarking precious metals for over 700 years. At the Goldsmiths' Company Assay Office we provide both traditional handmarking and the latest laser marking techniques across three key London locations with a choice of three priority services including one hour, same day and early hall. We process 3 million articles a year, in 100,000 packets, and are proud to apply the leopard's head townmark of London to each and every one.
