The Strength of Marble and Granite | Seattle Granite Marble

Each natural stone has a strength rating often referred to as its Mohs hardness. The Mohs scale of mineral hardness was developed to identify the strength and hardness of any natural mineral. For instance, if a stone has a Mohs hardness of seven, then that stone is solid enough to scratch another stone with a rating of six or lower.
