I did a mix of granite and quartz (Silestone). I have Kodiak granite on my counters and Tigris Sand silestone on the tabletop part of my island.

The Kodiak is creams and browns with a bit of peach, and the Silestone is cream with a subtle pattern on it.

Thank you for sharing. I love the colors you chose!

Michelle, I've posted these photos so many times before that I'm embarrassed to do it again! But since you asked, and since I mixed granite and quartz . . . I'll risk giving people terminal boredom

My island is Venetzian Polo, which is a rather highly textured granite. The perimeter is Zodiaq Eclipse Blue. We haven't settled on the backsplash, but the samples photo shows two things we're considering.

I love my choices. I do almost all prep on the perimeter countertops, and for me, the quartz is absolutely carefree. The only thing I'm careful of with it is pots just off the stove. The quartz cleans like a dream. The island is used for serving -- the texture makes it not good for things like rolling cookies or kneading bread (or writing lists!) but I love the texture so for me, it was a good choice.

For some reason, the floor shows up as very tan in this photo . . . IRL, the grey is much more apparent.
Here are the samples:

We didnt' mix quartz with granite, however we did use 2 types of quartz. Silestone White north on the perimeter cabinets, with Silestone olive green on the island. The island counter just went in today.
