Realistic photography of ancient Chinese jade artifacts. The main subject is a square seal made of pale celadon white jade, with a regular rectangular seal base. The jade material is milky white with a faint bluish hue, scattered with natural light green veins and minor usage scratches. The bottom corners of the seal base show brownish aged patina traces. On the top of the seal base, a coiled Chinese dragon knob is carved in the round. The dragon body features fine scale patterns, flowing mane, with the head slightly turned towards the front, mouth open showing teeth, and three pairs of dragon claws steadily supporting on the top surface of the seal base. The seal is placed on a dark gray matte display surface, against a pure dark gray gradient dark-toned background. Soft side-front lighting highlights the warm luster of the jade and the carved textures. 3/4 oblique angle medium shot, square frame, overall soft lighting, no extra decorations.
