The Rebel Gear jewelry was designed to look rugged, so don't fret if you notice your pieces are antiquing slightly. Sterling silver will naturally tarnish when exposed to common everyday items that contain sulfur, such as leather, rubber, chlorine, salt water, and even air pollution. We think these designs look best with some character, but if you decide you want to keep your The Rebel Gear pieces looking shiny and new, simply polish them with a silver polishing cloth — these can be purchased at most fine jewelry stores. All clothing items ship with individual care instructions on the inside label.
