Rare Art Nouveau style Sterling Coro Duette with stylized pair of flowers with a large pink iridescent type faux moonstone in the center of each flower. The design is simply fabulous with wonderful swirling lines. All pieces are marked sterling. The pat number is 1798867. The duette is 2 1/4" from side to side and about 1 1/2" from top to bottom. It does need to be polished, but I have left that to the new buyer. Excellent condition.
