It is a hard, dense stone resistant to scratching—a standard pocket knife won’t leave a mark. Its extremely low water absorption (0.10–0.18%) makes it highly resistant to staining, daños por congelación y descongelación, y la intemperie. The polished surface can achieve a gloss of over 100 degrees.
