Depending on the limestone and the mineral combination within the marble most marble rates from three to five on the mohs hardness scale.

Luster of marble is the interaction of light with the surface of marble. Marble is limestone that has been compacted and heated over millions of years.

The streak of marble is white whereas its fracture is not available.

To determine the hardness of natural minerals the mohs scale is used. One of the most important characteristics of alabama white marble is its strength. As a result marble is less porous and slightly stronger than limestone but still less durable than granite. Hardness hard although component mineral is soft calcite is 3 on moh s scale of hardness.
