Quartz is entirely different from natural quartzite. Quartz is primarily silica or silicon dioxide. It comes in many colors like white, gray, yellow, rose, violet, yellow, and brown. It is a crystalline stone and is very hard. Natural quartzite is a metamorphic rock that starts as quartz-based sandstone. It is mostly white or gray and is very hard, but more difficult to work with and not as abundant as quartz. Each has it’s unique strengths so make your choice based on your lifestyle.
