Also called gold overlay, gold filled wire is a great option for making precious gold jewelry without the cost of solid gold. Gold fill is created by using heat and pressure to apply a layer of karat gold to a base of less costly metal. This produces a thick karat gold surface that is 100's of times thicker than a plating! All of our gold fill wire is seamless, which means the overlay continues around the full circumference of the wire. Choose half hard or dead soft 14kt wire in 20 gauge to 26 gauge. We also carry a limited supply of clearance 12kt gold wire, while supplies last.
