Interesting and unusual shape rhinestone Tiara from approximately the 1920s though it might be a little earlier or a little later. It has a silver metal base and I love that the inside of the head band is finished with etched in scroll work. The Rhinestones are prong set with the very peak welded and fixed into place but with the strands connecting to the band left so that they have some movement. No missing or darkened stones. Fabulous!
