Quartzite has a Mohs hardness of 7, which is comparable to that of quartz and considerably harder than sandstone. Like glass and obsidian, it breaks with a conchoidal fracture. Its coarse texture makes it difficult to hone to a fine edge. Under magnification, quartzite's interlocking crystal structure becomes apparent.
