What is Mohs Scale and Why Hardness of Natural Stone is So

The hardness of any mineral is calculated on a scale of 1 to 10 which is called the Moh’s scale. This scale was designed by German mineralogist Friedrich Mohs in the year 1812, and rates minerals based on their capability to scratch or withstand scratches. A rank of 1 means the mineral is extremely soft, while a ranking of 10 refers that it
