Serpentine Antiques has dated this piece to the 1930s.

These large and remarkably heavy rings are oval in shape, and made in a very thick gauge of silver, with all over engraving, and with a very iconic geometric shaped blank cartouche, suitable for personalising if desired.

The unusual fitted case is shaped like a treasure chest, and lined with silk and velvet.
Size-2 1/8 inches long by 1 1/8 inches high.
Weight-130 grams silver only (over 4 troy ounces), 185 grams with case.

A really lovely heavy and iconic pair of napkin rings, in a unique style fitted case, and in very good condition.
They would make a fabulous gift, or a special treat for yourself.
