Looks like Chinese but you need someone to ID the bottom mark and the one on the underside of the lid. Most of the times the maker is of importance even if the piece is not very old.

That's it ! Is that what it says on the bottom? "Peach pit"

 

I don't think so, but I suppose it could be possible. The finial is a peach pit.
Hopefully someone can decipher the Chinese for you.

 

Is the peach pit made of clay, too? Or is it wood?

 

It's clay as well
