Antique Large White Jade Hanging Ball w/Brass Ornamentation

This is heavy and weighs about two pounds. Perhaps Chinese, a solid ball of white jade with slight green through it at places and with brass ornamentation four sides. This has been hanging from something, perhaps an old lamp, and there is a hook on the bottom so you can hang something else from it. The bottom detail is very interesting with a dragon and a bird. The ball is about 2 1/2 inches in length, circumference is 7 inches.
