Hallmarking

A hallmark is a series of stamps that are put on your jewellery by one of the assay offices to prove that it is real silver or gold etc. It is the mark of an independent valuation to clarify that the metal it is made from is genuine and that you are not simply claiming that it is silver when it is not.

It is a legal requirement in the UK to have precious metals hallmarked if it is silver over 7.78 grams, gold over 1 gram, platinum or other precious metal jewellery.

A hallmark consists of three punch marks:

• Sponsors Mark (the maker, or manufacturer) mark
• Metal and fineness (purity) mark
• Assay office mark (London, Birmingham, Sheffield or Edinburgh)

Purity Mark     Metal type
925                  Sterling Silver
999                  Fine Silver (as in most metal clays)
375                  9ct Gold
585                 14ct Gold
750                 18ct Gold
