How hard is limestone on the hardness scale? – Wise-Answer
Is limestone the hardest rock? These arbitrary labels are based on the premise that igneous and metamorphic (crystalline) rocks—granite and gneiss, e.g.—are harder than sedimentary rocks, such as limestone and shale. Calcite in limestone is quite as hard as that in marble, and the grains of quartz in sandstone are as hard as those in quartzite.
