Abstract

The present invention provides a method for engraving desired irreproducible patterns on the surface of gemstones including diamond by the use of an energetic ion beam. The pattern has a characteristic topological texture, which is irreproducible even using the same ion beam to engrave onto the same location of the same diamond.
