Carved with fine Hetian jade, this horn-shape has rich motifs carrying styles from late Chin Dynasty to early Western Han Dynasty. Instead of smooth unilateral edge for the opening mouth of the cup, it has wave shape to elaborate its unique style. On the top of the cup, a phoenix head and a dragon head are seen on each side. The empty space is decorated with low relief crop sprouts. The lower part has five passing through clouds dragons which are vividly carved with streamline bodies. The phoenix is holding a loose ring. Between the dragon head and the passing cloud dragon, there are a pair of rectangular curves which are Chin style typical motif. Antiquity evidences include cleaving veins, additive crystals and calcification.
