For your consideration is this large 1940s pink carnation brooch. Done is pink white and green enamel as accented by sparkly rhinestones. Probably pot metal.
It measures 3 and 1/2 inches by 1 and 5/8 inches across the widest points.
Fully functioning condition. Some enamel loss mostly in the green.. I believe the 2 open sections in the carnation are intentional. Stones look great with nice fire and look prettier in person.
