Hopefully the builder can confirm but perhaps the natural rope series from ELK?

Actually, both the island light and the light over the dining table are by Ironware International, and are available through O'Hara Interiors. Please contact them at design@oharainteriors.com for more info and pricing.

It's a little hard to tell in that photograph, but the dining table chandelier is entirely metal. There is no rope in that fixture.
