CARE AND MAINTENANCE Cleaning is recommended to maintain your jewelry's beauty. Wipe your chains carefully with a soft cloth to keep it clean and free of elements that oxidize. Do not overwork the plated materials, as you can wear off the plating. Most of my charms are plated, which means they have a heavy coating of gold or silver over hypo-allergenic brass or rhodium. The gold or silver can wear off as it comes into contact with the wearer's skin or friction. Therefore I do not recommend and do not warranty your piece, if you sleep, swim, shower, or exercise in your jewelry.
