The brass/glass DR chandelier in the house we bought was way too la-de-da for me, so I asked our electrician to take it down and put up my favorite Tiffany fixture instead. In the process, he shattered one of the panes. I looked in my VanDyke's catalog for replacement parts but found none. Is there a restoration company that would be able to help me? The shade is large [2'diameter]but uncomplicated, made of 8 large roughly egg-shaped amber and white panes. TIA,chery-va
