The invention discloses a stone lifting ring which comprises two end plates, two pin shafts are arranged between the two end plates, two rotating holes are formed in each end plate, and the two ends of each pin shaft are inserted into the rotating holes in the two end plates correspondingly and rotationally connected with the rotating holes. A pressing plate is fixedly arranged at the end, penetrating through one end plate, of the pin shaft, a threaded hole is formed in the other end of the pin shaft in the axis direction of the pin shaft, a bolt is arranged in the threaded hole, a pin hole is formed in the bolt, and a stop pin is inserted in the pin hole. The stone hanging ring has the advantages that the friction force between the hanging belt and the hanging ring is reduced, and the automatic contraction capacity is high.
