Yellow Rust Stone lychee skin stone is crafted by hammering the surface of the stone with a tool shaped like a lychee peel, creating a rough texture resembling the lychee skin. This texture is commonly seen on carved products or square stone surfaces, etc. It is divided into machine lychee surface (machine) and hand lychee surface (handmade). Generally speaking, hand lychee surface is finer than machine lychee surface but requires more labor and time.
