Sterling silver napkin ring made by Unger Brothers of Newark, New Jersey. The decoration on this napkin ring is that of one of Unger's line patterns called SIREN ON THE ROCKS.
This napkin ring is in extremely good antique condition with much of the original details of the harp/lyre playing naked woman sitting on a rock with waves in the background still sharp. The napkin ring is marked, but the marks are faint. Unger Brothers was out of the silver manufacturing business by about 1913.
There is a cartouche that was intended to hold a monogram and it is engraved.
I have had a few questions about the rim or edges of this napkin ring. In an effort to enlarge the images of the woman to show her detail, some of the edges of the napkin ring got cut off in the photo in the photo shopping process. These are not damage nor flat rims from being dropped. These "flat" areas are strictly from photo image enlarging. Image number 2 shows both sides of the napkin ring rims/edges. As can be seen, there are no flat rims/edges nor damage.
