This is a beautiful antique sterling napkin ring with fine repousse work. It is not marked sterling but has been acid tested by a reputable jeweler and is definitely sterling. For some reason the mark was never applied. The diameter opening is 1.75 inches and the width is 2 inches, so this is a large ring. In the cartouche are ornate engraved initials in a presentation setting. The monogram is just as handsome as the napkin ring. The weight is 1.7 ounces.
