  • Publication number: 20160120273
    Abstract: The invention is directed to a non-piercing earring comprising a front member, a rear member, a first magnet, a second magnet, a stop, and a compressible spring. The front member and rear member connect to form a hoop shaped earring. The rear member slides within an inner cavity in the front member. The inner cavity houses a compressible spring to generate a force pushing the rear member toward the user's ear. The terminable ends of the front member and rear member have magnets situated to provide an attractive force and further maintain the earring on the ear of the user.
