Connemara marble silver ring. The marble rotates. It's about a size 10. There's some scratches and tarnish. It would benefit from a polish. Although simple in its design, this sterling silver worry ring performs two duties. The ring looks beautiful on your hand thanks to its gleaming, round, Connemara marble stone and smooth shank. The cradle-like setting allows the stone to rotate freely, letting you spin it at will when you worry.
