An Adornment made of ivory

I took the picture of this ivory adornment in the Capital Museum in Beijing.

At the time, there's a show of the traditional Chinese handcrafts, a lot of lacquers and potteries were on show.

I really like ivory adornment so I took many photos of them. This one is amazing, the ball on its top is actually like a "matryoshka" (I found this word on the net, it's a kind of Russian doll), it means there are many balls one in another. Amazing!
