Gold vermeil has some key elements that make it distinctive and superior to gold plating. Vermeil is a technique originating in the 19th century, where real gold is applied to sterling silver. Gold vermeil is made in a similar style to gold plating but requires a thicker layer of gold. The gold layer must be above 2.5 microns, creating a finish that is five times thicker than average gold plating, and far more durable.
