Most of our jewelry is plated using 14/18K gold with a base metal of brass, sterling silver, or stainless steel. Plated pieces can be prone to oxidation, so we recommend that you avoid contacting with moisture and liquids. We suggest that removing them before you swim, shower, or apply lotion, sunscreen, makeup, or perfume. To minimize scratches, store your piece in your Made of Joys pouch or in a separate compartment in your jewelry box. If you need to clean your jewelry, use a soft cloth to wipe away dirt.
