Quartzite
Quartzite is a stone with the appearance of granite and marble. It's also stronger than either one, so if you want veining or swirls but don't prefer high maintenance for your kitchen worktops then quartzites are perfect!
Metamorphic rock is formed when heat and pressure Cause changes to an already existing sandstone. Quartzite comes from metamorphism, where it has been recrystallized into solid quartz by the silica cement that holds all of these grains together in what we call "quartz".
