All items on this page are composed of sterling silver,some containing gold filled accents. The black, or antiqued, items are sterling silver which has been oxidized. I finish all oxidized items with a sealing wax (don't worry-it's not sticky!)to help maintain a rich black color. Please note, however, that any item which is continuously handled over a long time can have the oxidation rub off. It will never go back to a bright white sterling this way, but the silver color will come through.
As these items are earrings, and not constantly rubbing on the skin, they will hold the black for quite a long time.
