Hallmarking Sterling Silver Jewellery
Under the current UK Hallmarking Act of 1973, all sterling silver items that weigh over 7.78 grams must be hallmarked at one of the UK’s Assay Offices. A hallmark is made up of 3 compulsory symbols which are the sponser’s or maker’s mark, the metal and fineness (purity) mark, and the Assay Office Mark. Sterling Silver jewellery that weighs under 7.78 grams is exempt from hallmarking.
Most of the jewellery that I make falls under the 7.78 grams weight and are exempt from hallmarking, but some pieces will still bear the 925 fineness mark. Any piece of sterling silver jewellery that weighs over 7.78 grams will be officially hallmarked by the Birmingham Assay Office and will be noted in the product description.
Jewellery FurKeeps is registered with the Birmingham Assay Office who carries out the hallmarking on all sterling silver jewellery that weighs over 7.78 grams and bears the 3 compulsory symbols which are my initials ‘ACA’ for the maker’s mark, the metal and fineness (purity) mark, and the anchor symbol for the Birmingham Assay Office.
