What Is Natural Stone?
Natural stone is a commonly used material in architectural decoration and is mainly divided into marble and granite.
-
Marble typically has rich textures and is mainly composed of limestone and dolomite. Its calcium carbonate content exceeds 50%. In a narrow sense, marble refers specifically to stone produced in Dali, Yunnan, but most marble used domestically today comes from other regions.
-
Granite is characterized by a speckled appearance and belongs to igneous rock, with a silicon dioxide (SiO₂) content of approximately 65%–75%.
Both materials are widely used for countertops, flooring, wall surfaces, and other applications in public buildings and residential decoration.
