This is such a fine bracelet. The clasp is hallmarked Plat. and 14K. The bracelet is Art Deco with 12 Diamonds and 6 Cabachon Sapphires. The Diamonds are small, but bright with lots of sparkle. Length of bracelet is 7" x 3/8". Weight is 12.2 grms. Condition is excellent. The bracelet has the same double safety lock that snaps on the top. Two hinges open the lock. I would date this beautiful bracelet at c1920's. I would say that the top of the bracelt is Platinum and the rest is 14K white gold.
