Vintage Bar Pin Open Filigree and Moonstone?

nice pin. featuring some decent filigree on the pin itself. I've seen this exact pin marked as moonstone. the effect here is a mithe of Pearl with a card eye that now we as you do. pin is 1.5" across and I believe an inch in height. the pin itself is modern in manufactured., while the stone is set in a cabochon. it is anniversary vintage pot metal pin in good condition.
