They are vintage so can not be purchased. There are some cool similar feel lights at www.rejuvination.com and I also just spotted these which are great too! http://www.potterybarn.com/products/basic-pendant-kit-whitney-fluted-glass-art-nouveau-shade/?pkey=cpendants&cm_src=pendants||

Thanks for replying! I have to make a quick decision on a small kitchen reno at a beach house and getting a late start. I like the polished nickel vintage look, your pottery barn suggestion is also nice. These will go over a bar area between kitchen and living room that is about 6 feet long so trying to figure out circumference size to go with and whether we should do 2 or 3. Do you know the length of the space where these are mounted and width of each pendant? Thanks!

This island is about 60x60. The pendants are placed about 10-12" from each edge with about 12" in between. I think the pendants are about 6" each? Good Luck!
