Thanks for your question. The way we work, our architects do not usually specify lighting fixtures, but leave those up to the client and/or interior designer. Also, that specific project was built over 10 years ago, so it would be challenging to say. Sorry we can't be more help.
In this wine cellar, heavy iron sconces look rustic against the stone covered walls. I'll bet if you were to look closely, you would see the hammer marks from hand forging.
Unfortunately we do not have the specified stone in our files at the moment.
