Vintage Unsigned Beauties Rhodium Plated Screwback Earrings Navette and Chaton Cut Stones

This is an exquisite pair of unsigned beauties. They are rhodium plated and have navette and chaton cut rhinestones in a pleasing conformation. They are 1x5/8" and have a patent number on the inside of the clip. The number is 156452 and I believe it refers to the clip itself.
