GORGEOUS VINTAGE 70’s sterling silver and amethyst stone handmade earrings

My hippi Mother- n Law gave me these from when she was much younger. Apparently they are from a very well known designer that she can’t remember the name of…. If anyone recognizes this style or possibly the designer, let me know. Embossed sterling silver with silver moon and stars with amethyst beads and set stones. 4” long Incredible design from the 70’s. She purchased these from Nepenthe in Big Sur.
