Warm, rich brass with green, white and blue enamel. Large glass rhinestone is central to the design and matches the beading on the piece. Peridot and blue rhinestones are used throughout for accent. Wears around the neck at 20 inches. The decorative plaque and glass drop is 3 inches. Absolutely beautiful. Unmarked but, has many elements of pieces from Czechoslovia. 1920's and is in very good condition. Does not disappoint.
