Every 20 minutes, the Diamond Lobby's main attraction, the fountain displays a giant Fortune Diamond, accompanied with music. This show spans 5 minutes.
At the start of the show, the accompanying music begins and the fountain exteriors are raised with the above chandeliers raising as well, to cover for the diamond rising. Then, the exterior fountain drops to reveal a large diamond spinning around with overhead lamps shining across it, displaying several colours. After its spin, the fountain exteriors raise again to hide the diamond and the fountain exteriors drop to its normal positions, thus ending the show.
