The famous granite in Hebei is Chinese black stone. With the export of other black stone varieties in China, such as black stone mining belts in Shanxi and Fengzhen, the mining of these similar stone varieties is also named Hebei Black and Fuping Black (different from other lower hardness stone types such as Mongolian Black and Fuding Black in basalt, black ore is hard granite). The hardness is high, with a Mohs hardness of 7. If you use a regular knife, you cannot make marks. When you hit it with a hard object, it will make a metallic sound.
