I am not sure John but it suits it perfectly. I have a lot of problems trying to find lampshades that suit. There is a limited supply of interesting ones. I have 2 great (not matched) Archimede Seguso lamps but cannot find the right lampshade for them.
Lamps are cheap compared to vases and large bowls, so I have bought around 15 of them and shuffle them around as the mood takes me THis one, however, is in the perfect place in the foyer of my house.
