Looks like white Carrara marble.

I'd say Calacatta based on the veining

I would love to know what the counter for the island is as well

Hello jendimerman, magicfamily, ndouble, emlinteriors, lauramat and lammy102! The island top is Calacatta Gold marble. We have similar marble slabs in our stocks and if you are interested in it, we can do the same island top for your kitchen.

The perimeter stone is a grey/green soapstone in a leathered or honed finish

The perimeter stone is actually honed pietra di cardosa, sealed/treated for a darker finish. The island slab is honed calacatta gold marble.

I was designing a similar style -thoughts if the island cabinets were dark smokey charcoal?
