I just looked at the photos of my fireplace slabs and I would bet yours is TM. It won't look as "white" inside your kitchen compared to the stone yard.

Only believe your own test results, not what anyone else says, please.

It's beautiful!

Hi all. Thanks. I’m no expert but this slab certainly doesn’t look like a granite. But what do I know? When I googled ‘White Pearl Granite’ the result is the typical ‘speckled with grey/black spots white granite’ photos. I’m going to do a test to this slab if this is indeed a granite or mislabeled quartzite, or god forbid marble as it’s really white or non-beige version of Taj Mahal.

@chispa If indeed this is a whiter version of Taj Mahal then It’s good because it’s a Quartzite. Because the beautiful beige Taj Mahal is a real hard quartzite. Like yours.

Though it’s veiny it’s subtle not like a calacata marble or calacata quartz, which are the veins that I meant as too veiny for the look that I want.

I have read the many threads about countertops by Karin the geologist.

Trying to educate myself as countertops cost serious dollars. Like everyone else here, I want a countertop that I don’t have to baby. My old kitchen had dark gray granite that was indestructible.

JF, I wouldn't say white, but mine have quite a bit of off-white in them. I would call and put those slabs on hold. Then get there asap to do the test.

In my area the TM slabs get sold pretty quickly. Mine were actually on hold for someone else. I asked for 3 slabs and said I would pay for them that day. They had to track the other person down and 2 days later the slabs were mine. Designers and builders go in there are put holds on a whole bunch of slabs that they don't always end up needing.

Hi Chispa. That’s what I’m gonna do, test the slab and finalize my choices hopefully next week. Countertop is my last big decision, and I just want this kitchen done. I wish that this White Pearl “granite” slab is indeed a whiter version of Taj Mahal quartzite and not some dolomite or marble or “soft quartzite. “

I don’t even know how I can do the etch test as the salesman said he doesn’t have any small piece for me to take home. I’ll bring a glass tile and try to do a glass test. But the sides of the slab are sealed or wrapped with a hard plastic or resin ?

I think this slab “White Pearl Granite” is actually White Pearl Quartzite” I am going to other slab yards to see “ White Pearl Quartzite” then see and compare, test if I can.

I think I’m gonna go with Taj Mahal. I found two slabs that A tiny 2 inch piece had came off and was able to test it. Red wine Vinegar super acidic did not etch and olive oil did not seep through. And my glass tile was scratched by the sharp edge of the TM piece. I even dab red wine vinegar on the unsealed Cross cut edge and did not penetrate.

Sounds perfect! Make sure you put them on hold before someone else walks in and buys them.

Just for the record, that slab in the OP is not granite in the geological sense. It's quartzite or marble.

And JF, it sounds like you're going about this exactly right. Nice work!

Hi Karin, thanks to you we here at houzz are all more informed about stones.

I did put them on hold @Chispa.

I know, I'm impressed with this community and how so many are helping to learn, use, and share the geology of natural stone. Pretty cool!
