Yellow Rust Stone Lichee Surface Stone is crafted by striking the stone surface with a hammer shaped like a lichee peel, creating a rough surface resembling the lichee peel, commonly seen on sculptures or plaza stones. It is available in two types: Machine Lichee Surface (machine-made) and Hand Lichee Surface (handcrafted). Generally, the Hand Lichee Surface is finer than the Machine Lichee Surface, but it requires more labor and time.
