Quartzite is a metamorphic combination of quartz, mica, and feldspar. Basically, quartzite is a metamorphosed sandstone, with a texture similar to slate. Pure quartzite is grey to white. Often, quartzite is streaked and patterned with pink, brown, or red deposits, most often iron oxides. These patterns form when sandstone undergoes great heat and pressure. Polished quartzite is very smooth and shiny. Polishing also emphasizes the color and pattern of the stone. Honed quartzite is a satin finish that glows gently. On floors, honed quartzite is preferred because it provides better footing and its finish will hold up better.
