Definitely chrome. Nice contrast.

I would go chrome.

I love brushed nickel just because chrome is more common so it feels more custom to me

I think brushed nickel looks common unless the hardware design makes a statement. That gorgeous countertop deserves something grand and out of the ordinary. Have you thought about a darker metal? Cast iron/cast iron look would be an unexpected contrast depending on your style. You could even away with matt gold. Polished nickel - my personal favorite - would look rich and elegant. If you're worried about a shiny finish competing with your collective elements you could choose a simple hardware design. I would play with some hardware samples of different styles and finishes and see what appeals the most to you. The samples you've shown in the photo give you a lot of options.

Definitely you need the sparkle of polished chrome! It'll look great!

What is the name of that absolutely gorgeous quartzite! with the farmhouse sink I'm not sure I'd go with chrome or even brushed nickel unless you find something less 'industrial'

If you use the white with gray stone on your perimeter you'll be fighting your star which is the island quartzite. I would pick a more solid stone for the perimeter and let the island be the star.

I feel you can never go wrong with chrome.

Anna I would go with a faucet in dark oil rubbed or black matte Lots of style out now and it doesn't even need to be farmhouse style. I love brushed and chrome but with that granite and farmhouse sink I'd pick something matte black.
