Firstly, the formation of granite requires very specific environmental conditions, including high temperatures, high pressure, and a long process of crystallization and separation. This makes the formation of granite very rare and valuable.

 

Secondly, the minerals in granite form large crystals during the process of crystallization and separation, resulting in each piece of granite having a unique texture and pattern. These textures and patterns can appear different from different angles and under different lighting conditions, making each piece of granite one-of-a-kind.

 

Lastly, granite has extremely strong physical properties that can resist natural factors such as weathering, erosion, and corrosion. This makes granite durable, long-lasting, and valuable for preservation.

 

In summary, the eternal and unique nature of granite comes from its rare formation conditions, unique texture and pattern, and durable physical properties. These characteristics make granite highly valued and widely used in areas such as architecture, sculpture, and decoration.
