The Strength of Marble and Granite Seattle Granite Marble

Marble is limestone that has been compacted and heated over millions of years. As a result, marble is less porous and slightly stronger than limestone, but still less durable than granite. Depending on the limestone and the mineral combination within the marble, most marble rates from three to five on the Mohs hardness scale.
