"A hallmark is an indication of metal content, a guarantee of purity or quality, which may include a maker’s mark and other marks.

The word hallmark is derived from London’s Goldsmiths’ Hall of the Worshipful Company of Goldsmiths, the originator of Britain’s first hallmarks, which still maintains a record of all British hallmarks. The most accurate definition of a hallmark is the mark or marks stamped, impressed, or struck on gold, silver, or platinum which indicate fineness or karat (also called quality or purity marks).

Hallmarks have been in use in England and France since the 14th century.The United States has never used hallmarks per se. Indications of fineness or karat have been required since 1906, but fineness marks were sometimes stamped on silver jewelry in the 19th century (“coin” or “standard” for 900 silver, “sterling” for 925)."
