The seal is made of gray jade with white sand-like spots on its surface. It has an inverted funnel-shaped knob with transverse holes. It has a square seal side with incised carving of "Liu He" in seal character. The characters are roughly carved, with missing strokes, so it should be a buried seal. It was discovered from the waist of the owner of the internal tomb where the silver-thread jade suit was unearthed.
