14K Gold Filled
"Gold Filled" is an actual layer of gold mechanically bonded with heat and pressure to one or more surfaces of the supporting base metal, then rolled or drawn to a given thickness. In the jewelry industry the quantity of gold must be at least 1/20th by weight of the total product. Gold-filled items will remain gold for a lifetime if cared for properly. The occasional silver spot is from solder holding joints together. Unless you are using harsh chemicals or abrasives, the gold layer will stay gold for years to come!
