This large antique white glass inverted dome ceiling light shade was salvaged from a damaged early 1900s hanging fixture (shown in the last picture at the estate from where it was purchased). It's about 14 inches diameter by 7" high from bottom center to the top of the 12" fitter ring. It has a matte satin finish to the exterior and a polished bright white milk glass interior. The shade is embossed with a classical cartouche panels and swags pattern.
There's a narrow 2-3/8 inch chip to the fitter ring edge, only about 1/8" of glass missing. This won't show once inserted into your fixture. See my other listings for a set of three matching sconce shades.
