ABSTRACT:
A smooth surface of a diamond or cubic boron nitride crystal is bombarded with ions sufficiently to penetrate the surface and impart an ion implanted region in the crystal in a predetermined pattern, the resulting crystal is charged electrostatically, and a powder is applied to the charged smooth surface producing a pattern thereon which is a delineation of the implanted region and can be used to identify or fingerprint the crystal.
