A diamond in one head, a ruby in the other head highlight this 18 K French serpent that encircles the finger. Each stone measures 3mm. We know that the snake symbolizes eternal love and was a particular favorite of Queen Victoria.
This shows the French mark on the exterior of the shank. We've tried to show it in the photograph, but it is not clear. The ring will fit a size 8 finger and could be resized by a competent jeweler. The ring sits fairly flat on the finger.
Lovely antique condition.
