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. Rectangular in shape with very geometric red and green champleve enameling. Measures just under 2" 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.
