For your consideration is this nice old navy ring, It has a cobalt glass intaglio accented with filler gold paint with USN and an anchor. They sides have eagles and nice detail and the words United States Navy run around the face of the ring. It is marked Sterling with a maker's mark.
The ring is a size 7 and 1/4. The face measures a hair over 3/4 inches top to bottom.
It is in nice condition. It could benefit from a cleaning. The glass is secure but does flaws - scratches and such. This is much more prominent in my enlarged pictures than to the naked eye.
