Victorian Ring Bird on Nest

Lovely and delicate, possibly Victorian, ring. Bird surrounded by leaves and flowers in high relief, glass beads are a robin's egg blue, one small glass bead is missing, see photos. Bird has red glass eye. Size is approx. U.S. 6.25 to 6.5. Face of ring approx. .5" x .5". Silver tone metal is untested. Very unique, very vintage!
