A hard granite stone material is rated higher if it scratches other material and not get scratched by it. If material is scratched by other material and doesn't scratch other, it means its hardness rating is lower. Things such as hue, crystals, and luster are also vital for deciding the granite hardness scale.

The hardness of any mineral is calculated on a scale of 1 to 10 which is called the Moh’s scale.

A rank of 1 means the mineral is extremely soft, while a ranking of 10 refers that it
