Gold Filled is a process in which heat and pressure are used to laminate the gold to brass. This is not to be confused with gold plating where a thin layer of gold is electroplated onto various base metal. The gold layer is 100 times thicker in gold filled then that of Gold plated, making it more durable and suitable for daily wear. With the proper care gold filled jewellery can last a lifetime. The gold filled findings we sell are 1/20th 14ct gold. This means that it is 14ct Gold bonded on brass and that 1/20th of the volume is gold and 19/20th's is brass.
