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.

Hallmarking arrangements during temporary closure of Assay Offices

Press Release from the British Hallmarking Council:

The pandemic has caused many disruptions to business across the U.K. The UK Assay Offices have of course been similarly affected and from the end of today all four Offices will be closed for at least three weeks.


Any business that requires product hallmarking or needs advice should contact the Assay Office they usually use and guidance will be provided.


The British Hallmarking Council is maintaining an overview of the situation and further information will be issued when Government restrictions are lifted.
