ABSTRACT:
An ornament includes a hollow ornament body having an inner coating layer in which a pattern is formed, to form an ornamental indicia for the ornament. The pattern in the inner coating layer may be a pattern of openings or a pattern of discolorations. The pattern in the inner coating layer may be formed by directing a laser beam through the hollow ornament body into the inner coating layer in a predetermined pattern. The laser beam may vaporize the inner coating layer or discolor the inner coating layer without harming the body of the ornament. The laser may be a Nd:YAG marking laser. Input patterns are provided to the laser after conversion from planar to spheroidal coordinates so that a pattern may be produced in the inner coating layer without distortion. When illuminated from within, the ornament produces a unique appearance because the ornamental indicia is illuminated due to the removal or discoloration of the inner coating layer.
