Unfoiled stones in open back settings. The pin is a "floral" motif with chatons and marquise stones. The 1 3/4" pin and 1 1/4" earrings are not a set.
The clip -ons have teardrop shaped dangles. However the coloring and finish textures are the same and unless you literally check to see matching stone cuts you'd never notice it. One chaton has a chip beneath a prong but, again, unless you're looking for it, you just don't notice it. Ca., 1960's and looks terrific on!
