Wow, this necklace is a stunner! The necklace is a generous 24 inches long and the pendant is 3 1/2 inches long by 2 inches wide. The back of the pendant is marked Sterling, 935, Austria, and also there are two other cartouches which I can't decipher. The reverse carved glass depicts a vase full of roses. The glass is open backed and bezel set. It is surrounded by light catching marcasites. There is also a black faceted glass drop for added drama. C. 1925 and in good condition.
