A formal dining room with a crystal chandelier, via Cote de Texas. My dining room table (120" without leaves, and there are three leaves) would be much better suited to a room this size!
Another Niermann Weeks Italian chandelier in a less formal dining room. This time, the lightness of the chandelier is a nice counterbalance to the heaviness of the table.
Most of the these dining rooms are elegant, but not super formal. The Caldwell-Beebe space is probably the most formal of the three pictures. However, the Niermann Weeks chandelier does not fit the bill of something reasonably priced that can stay with the house.
