Abstract
A novel technique for fine polishing surfaces of diamond to the submicron level involves applying to the diamond surface an oxygen-emitting polishing medium, either a dry powder or a powder dispersed in a liquid carrier. The diamond surface is then polished by high speed rubbing to a submicron finish by inducing oxygen emission and oxygen-carbon interaction. Several embodiments of apparatus for polishing are described.
