14K Gold Fill?

14K gold fill is the next best thing to solid karat gold.

In the U.S., gold fill is regulated by the FTC. By law, 14K gold fill must contain 5% pure karat gold by weight.

The gold fill process mechanically pressure-bonds solid karat gold to a core of brass or silver. Due to this fusion, gold fill gives you the weight and luster of solid karat gold at 1/5 the cost. It is also extremely durable.

Gold filled metal comes available to jewelers in three forms: sheet, wire and tubing (see diagram for proportions).
