Why do my silver beads become black?

Any piece of jewelry will begin to oxidize over time, as they are exposed to oxygen. As a result they will become black. Simply clean them with liquid soap and a soft toothbrush or polish them with a soft polishing cloth to bring back the silver shine. Do not use chemicals.

Do TPOA fit on a Pandora bracelet?
