Both sides of this disc are entirely covered with an orderly arrangement of scrolls carved in low relief framed by two very thin, smooth bands that run along the external and internal borders.
The original color and quality of the jade are almost imperceptible due to the heavy alteration which has almost totally covered the disc with a patina of chalky white. In the areas that are unaffected by the calcification, the jade appears to have a light green-yellow tone with some residual translucency. There is one small chip that is visible on the perimeter of the disc and some patches of red colour scattered on the surfaces.
