Bought a piece of jewellery, and unsure what it's made of? Found an old piece of silver amongst the family heirlooms, but don't know what it is? Or even if it's silver, or electroplate? We can tell you. Contact us and benefit from our knowledge and experience.

Our registers of maker's marks (now called sponsor's marks) go back to 1773. If you have a piece of Sheffield marked silver, gold or platinum, we can identify the maker/sponsor for you. We are also compiling a list of electroplater's marks and trade names, and have information on hallmarks from other towns and countries.

If you would like us to identify a mark for you, please fill out the form for the Enquiry and Research Service, and we will contact you with a price for the research.
