A very rare 18th century gilt silver mounted enameled porcelain bonbonniere or snuff box with blue john? (stone) set cover, realistically modelled as the head of a rather adorable dog. The box is unmarked and measures 2 ½ inches high by 2 ½ inches long by 2 inches wide. The number on the inside stone cover was affixed by the previous owner to identify his collection. Condition is excellent.
