Torbat Black Granite Stone with a completely uniform black color and no spots, is considered as one of the most consistent types of granite. Due to its lack of insulation, high porosity, inadequate adhesion to mortar in various weather conditions, susceptibility to airborne dust and the need for regular cleaning, and high volume mass, it is not a suitable option for external building facades and architects often use other black granite stones instead.

Torbat Black Granite Stone is used in all internal and external parts of buildings. This stone is very resistant to cold, heat, impact, and pressure and is one of the most suitable options for use in paving and interior facades of buildings. Other uses of Torbat Black Granite Stone include:

1- Paving of indoor and outdoor spaces of buildings

2- Interior façade

3- Staircase body and stair stone

4- Tombstone

The price of Torbat Black Granite Stone depends on factors such as color consistency, thickness, and quality of stone processing.
