“Quartz” is a man-made engineered material. Did you mean ”quartzite”? Quartzite is a natural stone mined out of the ground. Dolomite is not quartzite. Dolomite is a stone made from calcium carbonate like marble is. Dolomite is harder than marble, but will etch like marble. If the stoneyard is calling a stone ”dolomite quartzite”, it is dolomite and will etch, but is probably a beautiful stone. Many people put up with etching if they feel the stone is beautiful enough to make up for that. All the kitchens with marble counters go through that decision process.

Edited to add: I just googled and found this Quartz (i.e. manmade material), and the name of its pattern is “Bianco Dolomite”. That is just a name the manufacturer has given that color pattern, and has nothing to do with the stone called dolomite. If that is what you are talking about, then the vounter will have the maintenance properties of Quartz.

Did you ask the stone yard why it says dolomite in the name? Actually, no matter what they say (since they're in the business of selling the stone), it's great that you brought home samples to test.

In case you haven't seen them, here are some resources written by a geologist:

Thank you both for the responses. I didn’t ask at the time b/c I didnt know what dolomite was. I went home and tried to image search Domolite Grey Quartz (found nothing by the way) and learned that dolomite is a different type of stone entirely.

Also I will ask the stone yard but I don’t want to solely rely on answers from the people trying to sell me a counter!

If you are looking at stone (rather than the manmade quartz) take a good look at the granites. They are hard workers. So are the quartzites (not the dolomite kind) but their beauty comes with a big price tag.

Honestly I’m very focused on durability. I don’t want to baby the counters. I currently have quartz counters and they have been no work at all. That’s why I started out looking at quartz again.

I have had trouble finding granite styles that I like (white with grey/black veining). I hear mixed reviews on the durability of quartzite so I thought safer to just stay away. Maybe I should reconsider. Dolomite I never heard of until today!
