The ornamental design for a bellornament, as shown and described.
FIG. 1 is a front perspective view of a bell ornament showing our new design;
FIG. 2 is a front elevation view thereof, the rear elevation view being a mirror image;
FIG. 3 is a left side elevation view thereof, the right side elevation view being a mirror image;
FIG. 4 is a top plan view thereof; and,
FIG. 5 is a bottom plan view thereof.
The bell ornament I design is a flat-shaped Liberty bell with fish-eye design at the mouth of bell. Its surface can be smooth or designed with raised decorative pattern or patterned holes to give the overall visual appearance of the new design a more innovative and outstanding look.
