ABSTRACT:
Diamonds are marked by applying apertured stencils bearing identifying indicia to the girdles, applying a fusible coating material over the apertured stencils, and then heating the coating material to fuse the material on the girdles. The stencils can be eliminated, and the indicia can be formed by directing a source of radiant energy at the coating material, and by moving the source and/or the girdle relative to each other.
