PVD, short for Physical Vapor Deposition, is a vacuum coating method used to apply a gold layer to the base metal, used by luxury brands like Rolex and Cartier. G&J uses an extra thick PVD coating well above the industry standard. Compared to gold plating, PVD coatings offer superior resistance to corrosion caused by sweat and everyday use. This process results in a dazzling, functional finish, particularly effective when used with Stainless Steel as a base metal, ensuring it remains hypoallergenic. For those who prefer to keep their jewelry on at all times, PVD is an excellent choice due to its vibrancy and exceptional durability, lasting for many years!
