If you're still looking to source that gorgeous chandelier, I found an article noting that the designer is Cindy Rinfret - http://www.houzz.com/pro/rinfret/cindy-rinfret
Perhaps you can contact her directly and ask her about the light fixture.

I didn't see it noted, but here is the article crediting Cindy with the beautiful space: http://nehomemag.com/blog/design-depth-greenwich-style
