Abstract: A jewelry device comprises a unitary body having defined therein an aperture, a clamping member disposed within the aperture, and a shaft for displacing the clamping member between an open position and a closed position within the aperture. The aperture is sized to accommodate a part of the body to be decorated, such as the nipple of a breast, when the clamping member is in the open position. Once a nipple has been inserted into the aperture, the shaft is displaced so as to bring the clamping member into contact with the nipple, and thus grip the nipple. The device allows the strength of the grip exerted on the nipple to be varied. The device may be plated with a precious metal, and may be provided with any combination of adornments such as jewels, spikes, and studs, to increase its aesthetic appeal.
