Abstract
A method and apparatus for orientating discrete objects, such as gemstones, is described. The method comprises providing the objects on a travelling path; providing a pair of opposed walls () extending generally along the direction of the path; and generating relative oscillatory movement () between the pair of walls () and the travelling path (in a direction generally transverse to the direction of the path), so that the pair of walls () imparts lateral force to the objects to thereby urge them into their most stable orientation as they progress along the path. A device for checking the orientation of the discrete objects is also described.
