I claim the ornamental design for an anniversary ring, as shown and described.
FIG. 1 is a perspective view of the design of an anniversary ring;
FIG. 2 is a top end view of the anniversary ring of FIG. 1; and,
FIG. 3 is a side elevation view of the anniversary ring of FIG. 1.
The anniversary ring, as illustrated in the Figures of the Drawings, has a circular ring or band-like form, and consequently a high degree of symmetry. Thus, the top end view of FIG. 2 is a mirror image of a bottom end view. Likewise, any side elevation view of the anniversary ring, such as a right side elevation view or a left side elevation view, would be the same as the side elevation view shown in FIG. 3. For clarification, the design features illustrated on the inside diameter of the ring of FIG. 1 consist of twenty (20) blind apertures evenly spaced apart along the inner circumference of the ring. The design is configured for a total of 20 evenly spaced diamonds to be added to the outer diameter of the ring, one for each year anniversary for 20 years.
The features of the anniversary ring shown in broken lines on the outside diameter of the ring in FIG. 1 are for illustrative purposes only and form no part of the claimed design.
