Salt water and chlorine can damage your jewelry. Chlorine can damage and discolor metals that are alloyed with the gold and can slowly erode the finish and polish of gemstones. Also, lotions and sprays create a film on the jewelry, making it dull and dingy. To keep any tarnish or wear from setting in, take a soft, damp cleaning cloth and gently wipe off the surfaces of the jewelry, being sure to get in all the nooks and crannies. Keep jewelry dry. Moisture is the main factor that speeds up the tarnishing process. Store different types of jewelry separately. We recommend using a Ziploc or sandwich bag with the air squeezed out to prevent oxidization. Thank you!
