Abstract : Removal of non-diamond carbon from a diamond substrate surface is accomplished in an electrochemical apparatus comprising an electrolyte and spaced electrodes immersed in the electrolyte and having impressed voltage producing a sufficient electric field in the electrolyte to remove at least a portion of the non-diamond carbon. Removal of the non-diamond carbon is accomplished by disposing the substrate in the electrolyte without touching the electrodes for a time sufficient to dislodge at least a portion of the non-diamond carbon. The invention herein is also directed to diamond substrates having non-diamond carbon with a high resolution on its surface.
