" I believe this this is Cristallo quartzite of some sort but cannot find the exact name "

There are zero hard and fast rules with any natural stone. Any dealer can call it whatever they like realistically. Always get a sample piece and check it yourself for staining, etching and chipping.

With those dots it almost looks like granite so I’d look at granite and quartzite. Widen your shopping perimeter and be open to finding something else you love. You only have to go to the place once or maybe twice.

I did a Google image search, and what is coming up for me is something called Blanco Luma quartzite. Although as other are pointing out, names don’t mean that much in the stone trade.

Look up the old Geology threads by karin_MT for tests you can do at the stone yard to determine if it is a "real" quartzite or behaves more like a marble/dolomite.

Some slabs can be hard like quartzite, but porous like marble and those slabs need to be sealed regularly to avoid staining.

mine is a cristallo quartzite, I can see similarities to your stone.

Your counters are very pretty HU!

I agree with @Shasta to be open minded about granite. For example, this one that MSI calls White Valley is a little bit similar (although with less bold veining.) If you haven't yet, I think your best bet is to bring a sample cabinet door (and flooring if possible) to stone yards near you and do some exploring.

Visiting stone yards was my favorite part of my renovation, so if you need someone to tag along just let me know :)
