I believe these to be a vintage pair of Weiss Christmas tree earrings which were advertised in a November 1965 issue of The New Yorker as the "Sugarplum Tree Pin." Beautiful clip-ons. No signature that I can see. They are done in an antique-silvery-gold tone, the earrings feature prong-set sparkling Rivoli rhinestones in vivid red, blues, and Margarita or Watermelon -- green with glowing rose-colored centers.

Other features include a textured gold "rope" garland, graceful cut-outs and smaller pink and green rhinestones accenting the tree.

Very good vintage condition
Earrings measure 1 1/8 by 7/8 inches. Both clip-on earring backs are secure and hold well when closed.
