This is an incredible buckle created in brass with a champleve enameling in black. The black is so intense, it shows off as if it were velvet and it has a sophisticated etched design on the outer corners. It may have been silver plated at one time as there is silver wash on the back of one side. The buckle measures 4 1/4 inches long in all and 2 inches wide. It is from the Edwardian period of 1901-1910. Just beautiful!
