Please allow for 4~5 weeks to ship.) *Gold Vermeil is composed of a thick layer of gold over solid sterling silver. Industry standards dictate that the gold portion must be 10 karats or above for a piece to be considered vermeil in the U.S., but most high-quality pieces are 14, 18 or 24 karats depending on the thickness of the jewelry. The thickness of the gold portion is what really sets vermeil jewelry apart from simple gold plated pieces. The thickness of the gold portion must be a hefty 2.5 microns.
