Gold-filled” is a USA industry standard that legally requires 1/20th, or 5% pure gold by weight. It's a strictly regulated process that involves pressure bonding multiple layers of solid 14k gold with extreme heat over a core of high quality jeweler's brass resulting in a durable, quality real gold product.It is different from gold plated.Gold plated jewelry is jewelry made of a base metal  or silver that has a thin layer of gold applied to the top. The way we made is very durable but 14k gold filled is better if we have to do the comparison.
