Each begins with a standard 2 1/4\" fitter rim and measures 5 1/4\" in height by 4 1/2\" across. The shades are in very good original condition with only minor rim roughness. Each shade begins with an upper mottled section of blue/purple glass graduating to a fiery red orange when unlit and a brighter yellow orange when lit. Each shade is finished with a gently scalloped bottom edge. I believe these shades have always been a pair and were not put together after they left the factory. They are as close a humanly match as possible.
