Make way for the ludus rings. Safely embedded in the body of the stainless steel ring, moveable spheres of steel or synthetic coloured stones glide over the surface. They simply encircle the ring, cross it diagonally or gently sway back and forth. Any small movement by the wearer sends the spheres off on their orbit.
