I would date this elegant jewelry to the 1959's. It is superb and sparkling Eisenberg. The necklace is set with large rhinestone chatons. The center has a combination of baguettes, emerald cut rhinestones and that wonderful deco look icing overlaid in two places. Necklace is adjustable from 13 3/8" to 16 3/8". The center from baguette to baguette is 3 3/4" across and 7/8" wide at the widest part. The clip earrings echo the center with the icing. They are 1" top to bottom. All pieces are signed Eisenberg and are in excellent condition. They are rhodium plated for long lasting beauty. There is minor darkening on some of the rhinestones in the adjustable extension consistent with its age and use.
