Gorgeous vintage oblong monogramed napkin ring so pretty must see

This is a beautiful antique silver toned napkin ring; it is not marked sterling; very beautiful in person; the first initial appears to be "E", the middle may be a G and I can't tell what the last one is; this is oblong- I have several vintage napkin rings listed; happy to combine shipping. This one measures 3" long, 7/8" wide.
