A hallmark is an official mark or series of marks struck on items made of metal , mostly to certify the content of noble metals —such as platinum , gold , silver and in some nations, palladium. In a more general sense, the term hallmark can also be used to refer to any distinguishing characteristic. Historically, hallmarks were applied by a trusted party: the "guardians of the craft " or, more recently, by an assay office. Hallmarks are a guarantee of certain purity or fineness of the metal, as determined by official metal assay testing. Hallmarks are often confused with "trademarks" or "maker's marks". A hallmark is not the mark of a manufacturer to distinguish their products from other manufacturers' products: that is the function of trademarks or makers' marks.
