Awesome Unique Dangle Gold and Peridot Screwback Mobile-Style Earrings EUC

These are probably not actual peridot or actual gold, but just look!!! They really sparkle and move in such an interesting way. Who made them? No idea. The rivet, the screw-backs, and the prong-mounting of the stones leads me to surmise that they are a good quality set from the 1940's-1960's. I can't find anything else like them and there are no makers marks. Are these calling you?
