Vintage beaded evening bag, unique scalloped top

I believe that this gorgeous evening purse is from the 1950's, but I'm not an expert. NO designer label. The lining is silk-like with one side pocket and in excellent condition. In fact, the whole bag is perfect inside and out. It doesn't show wear, may never have been used. The cone shape, scalloped top, and zipper close are unique. I searched through hundreds of beaded purses and did not see anything like this. SIZE: 8" across the top, 7 1/2" long, hangs 18" from shoulder top to top of purse.
