Do you want to know what gold filled wire is?
IÂ use 14K Gold Filled wire and components in many of my designs. According to Wikipedia Gold-filled jewelry is a solid layer of gold bonded with heat and pressure to a base metal such as brass. The minimum layer of karat gold in an item stamped GF must equal at least 1/20 the weight of the total item. There is no standard for the thickness of gold-plated jewelry but you can expect GF items to be between 50 to 100,000 times thicker than gold plating. GF jewelry is heirloom quality.
