-Care for your Rachel Marie Waco Necklace by wiping it down with a cotton cloth after wearing to maintain its oxidized silver finish over brass base and prevent darkening of the patina over time. Use a 3M anti-tarnish square to store it separately from Sterling jewelry, as it tends to oxidize more quickly. Avoid wearing this necklace in water and always put it on after applying make-up, hairspray, and lotion for best preservation. The lobster clasp closure and 16"/18" chain length make it easy to wear and style as desired.
