Designs
Copper napkin rings may be rectangular, square or round in shape. They may have flared up or twisted design on them.
Techniques
Napkin rings are available in different sizes and in different finishes. They may be decorated with beads or simply with copper wires. Napkin rings are often made of hand-hammered copper. Some craftsmen engrave beautiful designs on the napkin rings. Copper napkin rings are usually seasoned with a time sealed finish, to prevent tarnishing.

Designer Silver Rings, Handcrafted Rings, Rhodium Silver Rings, Gold Rings, Beaded Rings with hung variety.
