That is a handmade chandelier, you can do a search on Etsy and surely you'll find somebody who makes it. Nowadays there's a lot of US based makers and lighting designers who create custom fixtures (myself included).

Feel free to check out My Chandeliers, I might be able to help you.

Note: I assemble my fixtures piece by piece, therefore the whole design can be made to fit your needs (I can get each one of the components used to make that chandelier).

This light fixture was purchased from a company called Lumin Light on Etsy: http://etsy.me/2iR9DzF
