Confirmed vintage Delizza and Elster (D&E) rhinestone brooch. Central variegated oval glass stone in turquoise, white and flecks of gold, surrounded by matte turquoise and white thin navettes and small chatons, in a swirled cyclonic pattern. Set in a hand-soldered goldtone setting. Measures 2" x 2.75". Excellent condition; I can discern only a very tiny chip on one of the white navettes.
This is an odd brooch for D&E, but confirmed by one of the authors of "Juliana Jewelry The Last Generation." Several color versions may be seen on the "Is It Juliana Jewelry" database website.
