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.
Claims14
A method of marking an object, comprising the steps of:
- a) applying a fusible coating on the object;
- b) exposing the coating to radiant energy in a pattern corresponding to indicia to be marked on the object, and heating the coating to fuse the coating to the object to mark the indicia pattern on the object;
- and
- c) adjusting an output energy level of the radiant energy to an energy level in which the coating material is fused and raised relative to the object.

A radiant energy marking system for marking an object, comprising:
- a) a fusible coating on the object;
- and
- b) a radiant energy source for directing radiant energy at the coating in a pattern corresponding to indicia to be marked on the object, and for heating the coating to fuse the coating to the object to mark the indicia pattern on the object;
- and
- c) a controller for adjusting an output energy level of the radiant energy to an energy level in which the coating is fused andraised relative to the object.
