Hi there, it's Caesarstone Quartz and the color is Blizzard.

I did a back-painted glass for a backspash. you get to pick your paint color, no grout lines, clean and simple, very modern, super reflective and depth, and way cheaper than quartz. Check out glass and mirror stores for their offerings. I went with tempered glass behind the cooktop.
