1939 CROWN TRIFARI Alfred Philippe Enameled Purple Flower and Green Leaf Necklace has clear rhinestone accents. The patent on this piece is 114137. It appears that the original fold over lock clasp was changed to a round spring closure. The necklace is approximately 17 1/4 inches long, adjustable downwards. There is slight wear to the enamel as would be expected of a piece of this age that has not been redone. Still in very good condition, this highly collectible design is a real treasure. The Trifari mark would have been on the original clasp closure, but the Des. Patt is on the back of the front flower motif.
