Possibly a DeLizza & Elster Unsigned Beauty Clipback Earrings from the 50s Light Sapphire AB Rhinestones in Silvertone Metal

This is a pair of unsigned beauties from the 50s. They have light sapphire and light sapphire ab rhinestones in a filigree setting. This type of filigree was used by D&E in alot of their jewelry. The backs of the stones would not be open as they are foiled stones. They did not put foiled stones in open back settings. They are in Excellent to mint condition. They are stunning.
