Abstract
A grown single crystal diamond is polished using a non contact polishing technique, which leaves a residue on the diamond surface. In one embodiment, a wet chemical etch is performed to remove the residue, leaving a highly polished single crystal diamond surface. In a further embodiment, a colloidal silica solution is used in combination with rotating polishing pads to remove the residue. Both residue removing techniques may be used in further embodiments.
