Quartzite is different than granite in that it is a metaphoric rock that is primarily made up of quartz. It is typically harder than granite, measuring a 7 vs a 6 on the Mohs scale (Diamond is 10). Quartzite has many of the same benefits as granite (resistant to scratching and durable under extreme heat) however one major variance exists, etching.
