What are gold hallmarks?
The hallmarking process has been happening in some form for centuries, as a means of identifying both the purity of a metal and the person who rated it. When you buy a genuine item of solid gold jewellery that weighs over a gram, you will see a small stamp, usually on the inside or another discrete part of the piece.
In the UK we have four assay locations: London, Birmingham, Sheffield and Edinburgh, where laser etching is used to avoid damaging the gold jewellery. Currently in the UK a hallmark is made up of four types of marks: the manufacturer’s mark, the purity, the assay office and the date of testing.
