What kind of granite or marble stone is Super White?

Hi there,
 
I've heard this word tossed around during renovations but unsure what it stands for.  Does it refer to a specific type of granite slab, marble slab, or does it refer to a specific type of finish on a kitchen countertop? 
 
Thanks in advance!

While some places call it a marble, a quartzite, or granite, it is in a class of its own. Super White is most like dolomitic marble. It's neither granite nor quartzite - it's not even close to quartzite in terms of hardness or resistance to acid.  Dolomitic marble is a sibling to regular marble, which can etch and stain easily.

Interesting, I assumed Super white granite or marble was just that-granite or marble. I didnt know that it was considered dolomitic marble.
