Rare! Incredible 14k Gold and Sterling Chevron Symmetalic Choker

Stunning Art Deco delicate statement necklace! 14k Gold on one side and Sterling Silver on the reverse. Symmetalic jewelry of similar design is generally from the 1930's. I have not seen that many necklaces so cannot accurately pinpoint the date. Marked "Sterling+14K Symmetalic" Very delicate and lightweight but high impact choker. About 14.5 inches in length and 23 grams in weight. Please review all pictures prior to purchasing and ask any questions. I am not a jeweler and the materials have not been tested by me.
