Antique Sterling Silver Enamel Vinaigrette with Chain Circa 1910. Art Nouveau Era enamel oval or egg shaped vinaigrette pendant and chain. This pomander necklace is enameled in a stark white guilloche on sterling silver. It unscrews to allow access to an interior compartment with space for a scent soaked sponge. The silver is sterling. It hangs from a sterling silver chain as well that is 19 inches in length. The chain is marked 925 Italy. It is a boxed style chain and perfect. Not as old as the Vinaigrette. The vinaigrette measures 1 inch long x 3/4 inch wide at the widest part of the enamel egg. There is no loss to the enamel. Perfect.
