Wonderful example of Sterling Silver Art Deco marcasite festoon necklace. Circa 1920's pieces are in excellent vintage condition with no missing stones or scratches on the onyx. Great patina build up over the years. Necklace has a 2 chain swag that holds the top part of the pendant that looks like an upside down fleur de lis. From this hangs the faceted rectangular onyx gem stone that is surrounded by marcasites. Necklace is 17" long and pendant drops 2" from chain. Earrings shown have their original screw backs and are also in excellent condition. They drop 1.5" from ear lobes. Drops are 1" by just over 1/2". I priced the pieces separately. I purchased them from the same estate but am not sure that they were originally part of a set even tho they are well matched. See listing #550 for price on earrings. This piece is not stamped sterling but have been tested.
