These vintage cufflinks have a gold finish. They are hand engraved "Belle". The only mark is a number "20" on each one.
Excellent condition. These date back to the first decades of the 20th century, at least. The oval plates measure about 3/8" by 5/8".
I am not sure if "Belle" wore these, or some lucky man was the recipient of this gift from her. I have additional cufflinks in my Mens Jewelry area.
