This is Artisan Stone Collection Calacatta Gold marble. I don't know of any granite that looks like this. You may check Cambria or Okite quartz for a look close to this.

There are few granites, mostly quartizes (natural stones) that have a similar look, although if you want an exact match in a natural stone you would have to go to the Calacutta Marble family. I'd look for: Super White Quartzite (a bit greyer nowadays than most pictures fyi), White Macaubas Quartzite, River White Granite, River Valley Granite, Taupe White Granite, Taj Mahal Quartzite (in a warmer tone), Fusion granite (sometimes colorful, sometimes much more subdued but you'll get the veining from this stone), Costa Esmerelda (sometimes spelled Costa Smerelda this is more of a subtle green, but it has the lilting lines that you might like if you like this one), and Valley White. Not all of these are matches, but if you like that one, maybe some of these will have the effect your going for.

What is the thickness of the miter? 2''??
