VTG AUSTRIAN Green Rhinestone Crystals Floral Pin Brooch 2.25” diameter

I did not find a hallmark but this is a stunning piece of jewelry. It’s in my keeper collection but willing to sell at asked for price. Poisenetta design with emerald green rhinestones cabochons. gold- tone patinas on sterling. Exquisitely designed. Looks to be gold foiled. The stones are brilliant. Circa unknown but prior 1980. Please note that the pin is slightly next but dies performance as expected.
