Hallmarks

Hallmarking is probably the first example of consumer protection law. In 1300 King Edward I enacted a statute ordering that all silver articles must meet the Sterling silver standard (92.5% pure silver), and should be assayed by ‘guardians of the craft’.

A hallmark is an official quality control mark placed on gold, silver and platinum and provides a safeguard to the consumer. An item’s hallmark signifies that it has been tested (assayed) by an independent body (the Assay Office) and guarantees that the metal is of one the legal standards of fineness, or purity. A hallmark indicates exactly what an item is made up of.
