Gold-filled earring hooks are a great option for making karat gold jewelry.
Choose from a selection of 12-karat and 14-karat ear wires with 1/20th gold by weight. Gold fill, also known as gold overlay, is made by using heat and pressure to apply a thick layer of karat gold to a base of less costly metal. This produces a surface of karat gold that is many times thicker than a plating.
