This is a lovely, nostalgic faux pearl festoon necklace from about 1935.  Tiny pearls (3mm) strung on string start from the box clasp and get gradually larger (7mm) until they reach the central portion of the necklace.   Three rows lace together from which four festoon garlands drape beautifully around the central drops.   Perfect for a bride or formal occasion.  The old box clasp of silver tone is nicely decorated with an embossed design decorated with four small rhinestones.  This is a beauty measuring 15 1/2" in length.  SORRY. THIS ITEM HAS ALREADY BEEN SOLD!
