14kt white gold 17" Vintage filigree rectangle necklace with bow motif, sapphires & 0.03ct diamond. This necklace was made from an Antique filigree brooch, which was the style in the late Edwardian period (1900-1915), into the Art Deco period (approximately 1915-1939). During the Edwardian period most of these brooches were in platinum, while during the Art Deco period they were more commonly made in white gold, like this charming example.
