Superior-Quality 14kt Gold-Filled Earring Posts with 4mm Flat Pad (12 Pieces)

Gold fill (also called gold overlay or gold-filled) is made by using heat and pressure to apply a layer of karat gold to a base of less costly metal. This produces a surface with karat gold. The minimum layer of karat gold must equal at least 1/20 of the total weight of the item. This is 50 to 100,000 times thicker than gold plating.
