The teapot is real ceramic with gold paint detailing. It is very cute, but also very small in proportion to the samovar/other accessories. I also don't know much about tea making since I don't drink the stuff, but does one really need both the samovar and teapot? Still, I give it an (A):
If the top of the samovar removes, try to place the teapot on top. This would be the traditional way to keep the teapot warm. It should nestle/fit on top if the proportions are correct.
