•Oxidized silver finish over brass base To properly maintain your jewelry, use a soft cotton cloth to wipe it down after each wear. Avoid wearing the jewelry while in water and wait until after applying make-up, hairspray, and lotion to put it on. Our jewelry has a patina finish that may darken over time. For storage, use an anti-tarnish 3M square and keep it separate from any sterling jewelry, which tends to oxidize faster.
