ABSTRACT:
A mechanism operative to allow various jewelry settings mounted to a ring, bracelet, or locket to freely rotate in an oscillating manner about a fixed center point. The mechanism includes a mounting base member having a perpendicular mounting stem affixed thereto arranged to rotatably support a pendulum member having at least one pair of oppositely disposed magnets radially mounted thereto for rotation about the stem within the base member. Superposed above the pendulum and freely rotatable about the mounting stem is a platform to which various jewelry settings are mounted, the platform also including a pair of magnets which are radially aligned with the magnets of the pendulum so as to be rotatably activated by the movement of the pendulum, wherein the identical magnetic pole of each pair of magnets is juxtaposed, one above the other, causing a repulsing rotational action therebetween.
