Antique 1.5” Head Hatpin ~ Variegated Blue Stone ~ Metal Flower & Rhinestones

Antique Art Nouveau hatpin ~ I believe the back and rim are brass ~ patent on the back but no date ~ multicolor blue glass disc with curved pieces of metal overlay to shape a flower ~ rhinestones at the joints and for the pistil ~ unique and beautiful hat pin ~  head measures about 1.5" in diameter ~ it's  about 9.75” long ~ good condition with some wear to the shank and has only a slight bend ~ the head has a pin that fits in the finding and moves a little but I think it's the way it's made, does not pull out
