Beautiful oval carnelian in the center of this Art Deco necklace is 1 1/4 inches long and over 1/2 inch wide and set in sterling. The fine paper clip chain is sterling also and the clasp is marked too. 17 1/2 inches to go around neck so it hangs nicely below the collarbone. Oh, and did I mention the sterling medallions with marcasites - nice. Necklace is for real from the 20's.
