We love these gold filled delicate rings that make the perfect stack! What Is Gold Filled? Gold filled products consist of an actual layer of gold that is pressure bonded to another metal. Gold filling is one of the most valuable and tarnish resistant processes for creating gold jewelry and other items. If properly cared for, your gold filled product can last a lifetime and thanks to its durability, there's no need to worry about wear. Gold filled jewelry is actually an economical alternative to solid gold.
