Abstract: A method of processing a super-hard material having a Vickers hardness of no less than 2000 kg/mm2, the method comprising: (a) forming a surface of the super-hard material to have a first surface profile within a first root mean square deviation being no more than 5 μm; (b) analyzing said surface of the super-hard material to detect a plurality of protruding regions on said surface; and (c) selectively processing over only the protruding regions on the surface of the super-hard material to form a second surface profile within a second root mean square deviation from the smooth target surface profile, said second root mean square deviation being no more than 100 nm.
