How is marble graded?

Marble grading is primarily based on the characteristics in fabrication. This includes considerations such as the stone’s structural integrity, surface finish, the consistency of color, and any flaws or imperfections that may affect its aesthetic appeal and usability. These characteristics play a crucial role in determining how the marble will perform in application, how well it will hold up over time, and how suitable it is for specific projects.

While attributes like color variation, hardness, and size and thickness of the stone do have importance, they are not the principal factors in grading. Color variation is more about aesthetic preference than grading criteria, hardness is often more relevant in comparing different stone types, and size and thickness are typically specifications for particular applications rather than grading attributes. Therefore, understanding the fabrication characteristics gives a clearer picture of the marble's overall quality and practicality for use in flooring and other applications.
