There’s no way for us to tell.

Are you sure it’s quartzite, and not quartz? Looks more like quartz to me.

Google image search says it is Calacatta Ghiandia quartz. Not a quartzite.

I thought so. It looks nothing like real stone, which quartzite is.

It’s a screenshot of a video. The user said it was a quartzite

The user is wrong. Many people aren’t aware there’s a difference.

I found it that it’s called Ljen blue Quartzite. Thanks everyone!

Good for you--it didn't look manmade to me. The veining was too random--most quartz materials have thicker more uniform veining.

Google Image Search is frequently incorrect., FYI

Whatever…it’s not exactly an attractive stone.

Thanks for sharing! Sounds like you’re more of a quartz person, and I’m more of a natural stone person

Ha! If you’re referring to me, I despise plastic filled quartz. Just because a slab is natural stone, doesn’t automatically make it attractive.

Anyone who has frequented this site over several years, has seen my soapstone kitchen…purchased from and installed by M. Teixeira, the soapstone experts.

Btw, should you proceed with that quartzite, make sure to test it. Many quartzites, although very hard, are porous. There are many threads you can search for, on this topic.

@darbuka - just because you don't like the slab the OP has posted doesn't make it objectively an "unattractive stone." Insulting the OP's taste isn't helpful or needed.

Just like @Diana Bier Interiors, LLC commented - it looks like a natural stone to me. My initial thought was that it was Ijen Blue Quartzite - which it still may be. However, it could also be Calacatta Fabbricotti marble:

Just like Ijen Blue Quartzite, Calacatta Fabbricotti marble slabs are all unique. Both stones have similar colors (which includes some blue). I've seen some very pretty Ijen Blue Quartzite slabs.

Ijen Quartzite is more common than Calacatta Fabbricotti marble = it's easier to find = it may well be Ijen Blue Quartzite. I just wanted to make you aware that there is a marble that looks similar to what you've shown. Just make sure that you test any slab in order to confirm that it's quartzite vs. marble (easy to do - simply use some vinegar on it - marble will etch immediately).

When you find some slabs that you like, please come back and show us - just ignore any negative comments re: your selections (fortunately, they are rare).

I think you mean Ijen (capital i) blue quartzite.

Several members have used it over the years on Houzz. Here is a search for discussions on Ijen.

Beautiful stone - i am amazed they could do that front detail give how hard quartzite typically is

Thank you, everyone, for all the helpful advice and encouragement. I’ll definitely test any slabs I seriously consider and will share an update when I find the right one. One of the things I love most about natural stone is that every slab is unique—I honestly don’t think I’ve ever seen an ugly one. I’m excited to find the perfect fit for my space.

Get what you love! I have leathered Taj in my master bathroom and Leathered Monte Cristo in my kitchen. Some say it’s a waste to do the satin or leathered finishes but I don’t like seeing fingerprints and smears from cleaners on my friend’s polished Taj…
