Brooch Vtg Unsigned Austrian Blue AB Rhinestons Pinwheel Design Brooch

This is an unsigned vintage stunning blue aurora borealis crystal rhinestone pinwheel design brooch. It features beautiful blue AB crystal rhinestones that give off warm golden highlights. The center starts off with a large AB chaton that is surrounded by 5 blue chatons. Those chatons have a medium-sized AB chaton at the ends. Between the blue chatons, it has the tentacles that make the pinwheel design. This brooch is not signed, but in my research, I found an identical one on Etsy that was stamped "made in Austria". The only difference is the setting. This is in a gold tone. The one on Etsy is in a silver tone. The style, stones, and construction are consistent with Austrian rhinestone jewelry, so I would say that it is made in Austria, although I am not sure of the date it was made. The rhinestones are clear and sparkle beautifully. I would say that it is pristine.
