This wonderful American sterling napkin ring is marked "sterling" (see picture). The floral repousse work is extraordinarily fine. The work on both the flowers and leaves is intricate and beautiful--especially the design of the cartouche. Note that the name "Grandpa" is engraved inside the cartouche. The diameter opening is 1.75 inches and the width is also 1.75 inches. It weighs 1.5 ounces on a postal scale, considerably heavier than a typical sterling ring. The napkin ring has been well cared for and is in outstanding condition.
