Quartzite is harder than its parent rock quartz sandstone, because in quartzite, the quartz has been altered and recrystallised, forming the cement between the quartz grains. In sandstone, the cement is often other minerals such as clay minerals or siderite (iron carbonate).

Quartzite is a metamorphic rock formed of sedimentary stone that has been 'baked' by the earth's heat and recrystallized into a harder rock.
