This is the most magnificent rhinestone butterfly I have ever seen. It is a rainbow of jewel-tone colors. The large top wings sit slightly above the smaller bottom ones, giving it dimension. It is set with different sizes of rhinestone navettes and chatons. The outside of the butterfly is a row of small chatons. All stones are prong set and even the feelers have a rhinestone tip. Metal is goldtone. This is unsigned Weiss and is shown in the "Jewelry 101" or Jewelry 202 book. I am not sure which one it is. Brooch is 2 7/8" across and 3" top to bottom. It is in excellent condition with sparkling rhinestones and no loss to the metal. Please look at the construction and the way that the stones are set...it is superb! The colors are deeper than they appear in my photos.
