HUGE Dragonfly Pin in Sterling Silver with Golden Banded Sardonyx

Huge vintage handmade sterling silver dragonfly pin. This outstanding piece is set with bright golden red banded sardonyx. The eyes are dark brown agate. It measures 2 7/8" tall with a wingspan of  2 7/8". It is tarnished and in original patina.

The beautiful arch of the antennae just makes this piece look rustic and elegant at the same time. One of them is broken away from the head, but was not moving at all because of the arch. I tacked it down with metal glue and it is holding. Soldering it would melt the little bead shapes of the wire. 

It weighs 29.2 grams. No hallmarks. Acid tested.
