Definition: Gold-filled is often heard when it comes to wire jewelry because gold-filled wire is pretty popular when it comes to wire wrapped jewelry designs and other jewelry that uses wire. For example, the earrings pictures, Amazing Butterfly Crystal Dangle Hoops, include gold-filled hoops and gold-filled head pins.
While gold-filed metal has many layers of gold, it is not pure gold. On the upside, gold-filled is of much better quality than plated gold (only one layer) so gold-filled lasts for a very long time if cared for properly. Gold-filled allows you to have the look of gold but without the price.
