What is hallmark meaning?

Hallmark refers to a mark or a series of marks applied to an object as an indication of its origin, purity, quality, or authenticity. The term 'hallmark' may also be used to refer to the system of testing and marking goods with such marks. In the jewelry industry, for instance, a hallmark may indicate the metal content or purity of the piece, the manufacturer or country of origin, or the date of manufacture. The use of hallmarks helps to protect consumers from fraud and ensure that they are buying legitimate products. Hallmarking is regulated in most countries by government agencies or industry associations.
