It might be Super White quartzite or Matarazzo White quartzite. Note that I said quartzite, which is a mined stone, not Quartz which is a man-made material.

Thank you!

It could also be marble. It's hard to tell. I can tell though that it is not Quartz.

I was hoping that it was quartz. We’ve had 2 slabs of quartzite on hold for months and when they took them out to cut them, one had what looked like grease spots on it and no one could explain why so we are starting over 😩

Much too glossy to be engineered stone. Looks like mitered sintered to me.

@Joseph Corlett, LLC, porcelain slab is a good guess with that shine, but look at the sink. Do they miter that 3 cm sink edge too? I thought that color/pattern did not go all the way through with porcelain?

It looks a lot like my counter. Mine are Aries white granite.

Good catch. Some of the sintereds have the color and movement go all the way through. Tough call from a picture.
