Faberg's Eggs: One Man's Masterpieces and the End of an Empire - Toby Faber

Faber seems to lost interest after the fall of the Czars, but who can blame him. It's also rather strange that he seems more concerned about Faberge's sons reaction to their father's activities outside of marriage, and not so much interested in their mother's.

Still, it is a rather good book and does flesh out knowledge of the pieces.
