Art Nouveau butterfly sash pin , green glass stone, Downton style, ZEN

This is a gorgeous art nouveau metal butterfly sash pin. It has an oval green glass stone in the center which has one small chip at the top as you can see in the pictures. Still the pin is quite a looker ! It measures 3.5 x 2”. Has a straight plain pin on the back .Great style to this one ! Price reflects damage on the stone. Thank you so much for looking !
