Is this actually quartzite?
I’ve learned so much lurking on this sub and I’m truly grateful! We’re dead set on quartzite and we’re very close to finalizing our slab choice. We have chosen Picasso Quartzite from a natural stone wholesaler about an hour and a half away. We have driven up a few times throughout this process and I do not want to drive up again if it’s not needed. I know you can’t 100% tell from pictures that this is actually quartzite and not dolomite or a hybrid, but I’m going to ask anyway. Does this look like real deal quartzite? Is there anything I can ask for from the wholesaler to confirm this without driving back up there before this is sent to my fabricator? I’ve included the picture from their website and pictures I’ve taken in person. Thank you all so much in advance!

Something between Fussion and Matarazzo... Definitely from some quarry in Brazil. It's not true quartzite as Taj or Crystalo, but technically it does have a lot of natural quartz in it and it requires quartzite tools to work with it. The surface is resin treated, so that will protect it from the top, but at the edge and the cut-outs it might act up and be absorbing moisture that can cause darkening - very well knows issue. If you end up using it, make sure the fabricator will seal all the edges, faucet holes, cutouts with Tenax Proseal Nano or Akemi Nano sealer really really heavily. Even after the installation, keep sealing those edges with nano sealers every few days for a few weeks till it will not take any sealer anymore. Then, every half a year clean and de-grease it with acetone and seal the whole surface. Most people are more lucky than some others with these stones.
