Girdle buckle

The image shows a white jade girdle buckle carved into the shape of a crab. The crab has a rounded body with a textured surface, and its legs are carved out of the jade with thin slits between them. The top of the crab has a decorative design with curved lines and shapes. The number "573" is printed in black at the bottom of the buckle. The background of the image is black. The buckle appears to be an example of a type of jewelry, likely from an artist.
