Worried about losing the backings on your favorite sterling earrings? Have us switch the posts and ear nuts over to the Protektors! The ear nuts have a locking mechanism, which needs to be squeezed on either side in order to take the earrings off or put them on. The pricing includes labor and materials, but not the main portion of an earring. You can use this option to send in your own earrings, or select this option when ordering a new pair of Sterling Silver Earrings and we’ll have the Protektors installed for you before sending the earrings you purchase.
