What is 14kt gold filled?

It is a layer of 10Kt or better gold mechanically bonded under heat and pressure to one or more surfaces of a 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. Under FTC regulations, a product may be marked as 14, 12 or 10Kt Gold-Filled. Karat measurement of gold content must be part of the marking.

These are minimum standards.Thus one might find 14/20GF or even 14 /10GF as a stamp to denote 1/20 14Kt Gold-Filled and 1/10 14Kt Gold-Filled.

Gold-Filled items are generally considered life-time products, and the gold layer will not wear off, as it will in electroplated products.
