All of our jewelry is made with 18k gold PVD plated stainless steel and built to last. The base metal is durable, tarnish-resistant 316 stainless steel, coated with a thick layer of 18k gold using a special PVD process. This makes it 10x more durable than standard gold-plated jewelry! It’s also hypoallergenic, so no green skin or irritation—plus, we never use lead or nickel. To keep it shiny and beautiful for years, avoid water, liquids, and harsh chemicals.
