The difference between gold filled vs. gold plated jewelry is that gold filled is of a higher quality. Also refered to as rolled gold and is at least 5% gold content by weight. There is 100 times more gold in gold filled wire vs. gold plated. Gold filled wire is bonded to a base metal (brass alloy) with heat and pressure. The exterior of the wire is solid 14K gold. Gold filled wire is a very high quality jeweler's wire. It will never tarnish, chip or wear away. The gold filled wire I use is either 14K or 12K gold. The jewelry made with gold filled wire will last you a lifetime!
