The ornamental design for a christmasbellornament, as shown and described.
FIG. 1 is a front perspective view of a Christmas 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 Christmas bell ornament I design is a round-shape bell with flat curves on its right and left side. 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.
