Our pieces are made to last. They are made of 916L stainless steel and plated a thick layer of 14k gold. We use PVD for gold plating, a process that uses Physical Vapor Deposition for coating our surgical grade stainless steel. This technique is the most resistant to corrosion from sweat and regular wear. You can work, swim, workout, shower, simply go about your day and you never have to take your jewelry off.
