I tried to determine the same thing, after also seeing/learning of wicked white at Gerrity! I couldn't get an actual sample of the ones they called wicked white, but my tests with super white (from other locations) did etch. It is a gorgeous stone but I opted not to get it.

Is yours installed yet? I bet it's beautiful, would love to see pictures!

I don't have the answer to your question but after a trip to one of our region's largest stone yards last week I can tell you that confusion abounds about what is what.

DD and I spent hours there and got conflicting information from different sales reps when we inquired about stones. And while I can understand why pricing can only be given through a fabricator, I don't know why they can't label if a slab is granite, soapstone, marble, quartzite, etc.

I am a geologist.

Quartzite is a stone made of quartz SiO2 which has undergone natural pressure such that breaks occur across the quartz grains.

Marble is CaCO3, and may or may not be a result of natural pressure. Marble is a lot more at risk of being 'etched' by acids (like vinegar).

Soapstone is a metamorphic rock that has naturally undergone heat and pressure. It used to be used for chemistry lab surfaces as nothing would etch it.

Granite is an igneous rock.

A rock cutting operation cuts massive slabs of solid rock into slices with long diamond saw blades.

Matching some rocks is like matching some wood patterns; you almost have to have adjacent slices for the duplication of patterns to look 'right' and/ or symmetric.

it is installed and it is beautiful. thanks. what did you go with, kitchen-reno?

I went with leathered Jet/Virginia Mist. It's a completely dif look than the Wicked White but I love it!!!

Love it on your island! What is your perimeter stone?

honed AB.

Your wicked white is wicked gorgeous! If we had anything like that around here, I would have pounced on it. I'm going through the countertop hunt right now. It is very frustrating. Absolute black and carrara are what I like. Not sure yet which will go on the island, and which will go on perimeter. Your kitchen is lovely!!

the stone yard confirmed that Wicked White is a true quartzite and not a dolomite. not that i could do anything about it now, since it's been installed! but i just wanted to know what i had in my future. hopefully it's the truth!
