Our jewelry can be worn in the water and are tarnish-resistant. Plated jewelry has a thin layer of gold or silver electroplated over a base metal. All of our pieces are gold plated with at least 0.1 micron of 14K/18K Gold or Silver. The base metal is either stainless steel or sterling silver, see each product's description for more details. Since these pieces are not solid gold their color can fade over time. Proper care will keep jewelry shining and living its best life.
