Abstract : Process of smoothing or polishing a diamond surface to reduce asperities thereon to a level as low as about 20 nm from the horizontal by implanting the diamond surface with ions to form a non-diamond carbon damage layer on or below the diamond surface below the disparity depth and dissolving the non-diamond carbon by submerging the non-diamond carbon in a liquid having sufficient electric field to dissolve the non-diamond carbon.
