Be sure not to put hot pans on quartz surfaces, they can scorch. Likewise do not use quartz as a backsplash behind a cooktop or range.
Quartzite, which is real stone, is beautiful but some of it being sold today is mislabeled marble, for instance Fantasy Brown is really a marble and will etch. If you were still interested in going this route, I would advise you to do your homework
