Elegant quartzite is a hard metamorphic rock which was originally sandstone, which features rich colors such as vibrant blue, jewel-like green, and brilliant yellow. When the sandstone is metamorphosed to quartzite, the individual quartz grains recrystallize along with the former cementing material to form a beautiful interlocking mosaic of quartz crystals. Quartzite’s resistance to chemical weathering makes it ideal for a variety of uses in commercial or residential construction.
