Pendant: Stainless Steel Plated with Silver or Gold ★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★ Sterling Silver jewelry is an alloy that contains a mixture of 92.5% pure silver and 7.5% of another metal, usually copper. Sterling silver is safe for sensitive skin; however it must be stored in a dry dark place as overtime it will tarnish. It can be restored with a silver polish cloth. Gold-Filled Jewelry employs a process in which gold is bonded to a base metal alloy such as nickel or brass. All exterior portions are solid gold and safe for sensitive skin.
