Gold Purity Marks
The letter “k” refers to karats, where pure gold is composed of 24 karats (24k). A piece of jewelry with an etching that reads “18k” or “750” indicates that it is made up of 75 percent gold, while a “14k” or “585” mark indicates the metal is constructed with 58.5 percent gold.
Most other letter markings indicate that a piece is gold-plated or gold-filled. Gold-plated pieces may be marked 'GP,' 'GE,' or 'HGE. ' 'GP' or 'GE' means the piece is electroplated with a thin layer of gold; '18K GP' would indicate a piece plated with 18 karat gold.
