What is hallmark?

A hallmark means the article has been independently tested and conforms to all legal standards of purity/fineness. It is a set of symbols applied on a jewellery made from precious metals such as silver, gold, platinum or palladium by assay office. It is made of 3 compulsory symbols.

    • The Sponsor’s Mark: It is a mark of company or individual who is responsible for hallmarking. In the UK this mark consists of at least two letters within a surround.
    • Metal and fineness (purity) Mark: This shows the fineness of the metal. Indicates the precious metal content of the article and that it is not less than the fineness of the article indicated. The fineness is indicated by a millesimal number (parts per thousand) and the metal type is indicated by the shape of the surround.
    • The Assay Office Mark: This symbol shows which assay office tested and marked the item.
    • Traditional Fineness Mark: The traditional fineness symbol is optional.
    • Date Letter Mark: The date letter mark is optional.
