Cup and cover

The Metropolitan Museum of Art

The image shows a green stone cup and cover. The cup is spherical with a small lip around the top and two small curved protrusions on opposite sides. The cup is a mottled green color. It has a small circular opening at the top. The cover is not visible but implied to be present. The cup sits on a dark brown stand with a wide base and three legs. The stand has ornate carvings on it. The background is a plain gray color. The overall style suggests it may be Chinese.
