Quartzite has a grainy, sandpaper-like surface which becomes glassy in appearance. Quartzite (from German: Quarzit) is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone.ure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of iron oxide (Fe 2 O 3). Other colors, such as yellow, green, blue and orange, are due to other mineral impurities.
