A method of polishing material for lapidary and like purposes, the material and abrasive being tumbled in a vibrated container which alternately compacts the material against a wall of the container and then separates it in order to reduce the time required for polishing. Apparatus for carrying out the method vibrates the container of the material and abrasive so that a portion of its orbit is about a theoretical center which is above and to one side of the center of gravity of its mass.
