Exceptional circa 1920's to 1930's vintage guilloche enamel over brass woman's belt buckle. Buckle was purchased in Germany. I was told they were German but however could also be French. Elongated in shape with very geometric black and white champleve enameling. Measures just under 1-3/4" long by 1" wide. In excellent vintage condition with no enamel loss. I acquired a collection of them which I have listed as well. I can see these buckles in their traditional use but they would also make great accessories for a bracelet design.
