Sterling Silver Set Onyx Rectangular Swivel Back Cufflinks

The UK Hallmarking Act 1973, as amended, requires that all items over 7.78g (for sterling silver) and 1g (for gold) carry a UK hallmark from one of the four Assay Offices in the UK.  Stamps such as "925" and "375" are applied by some manufacturers, and although indicative of the metal purity, are not full UK hallmarks, and should not be confused with UK hallmarks.

At jewellerybox we hallmark all items of gold & silver above the UK hallmarking weights.  Items below these weights may carry a hallmark, but we would not hallmark such items as a standard.  As an Assay Assured jewellery retailer we are dedicated to providing a high standard of product, and we work closely with the Edinburgh Assay Office and the Birmingham Assay Office in maintaining strong compliance procedures.
