  • 1What is a Hallmark?

    • a Hallmark
    • Consists of a series of marks applied to articles of the precious metals platinum, gold, palladium and silver

    • Means that the article has been independently tested

    • Guarantees that it conforms to all legal standards of purity (fineness)

    • A complete hallmark consists of three compulsory punch marks:

    • Sponsor's (or maker's, manufacturer's or name) mark

    • Metal and fineness (purity) mark

    • Hallmarks can be applied by traditional punch or laser.
  • 2Why Hallmark?

    Precious metals are rarely used in their purest form but are usually alloyed with other metals. It isn't possible to detect an article's precious metal content by sight or touch. Therefore, it is a legal requirement to hallmark articles containing precious metals if they are described as such.


    The UK Hallmarking Act (1973) states that it is an offence for any person, in the course of trade or business, to describe an un-hallmarked article as being wholly or partly made of precious metal(s) or to supply un-hallmarked articles to which such a description is applied.


    Dealers are required to display on their premises the statutory notice which describes the approved hallmarks. It is an offence for any dealer to fail to exhibit or keep exhibited the notice. 'Dealer' means a person engaged in the business of making, supplying, selling (including selling by auction) or exchanging articles of precious metal or in other dealings in such articles.
