I have just one book on Faberge which doesn't seem to have been mentioned yet ~ it's rather old but I've treasured it for many years now. It's a big book, called 'Peter Carl Faberge, Goldsmith & jeweller to the Russian Imperial Court and principal Crowned Heads of Europe : an illustrated record and review of his life and work, Ad 1846 - 1920', by Henry Charles Bainbridge. Published 1949 and dedicated to HM Queen Mary. The written style is rather flowery and old fashioned now, but the plates are wonderful ~ 126 of them with excellent chapters on the man, his work, his clients etc. I bought it after I had seen the Faberge objects in the collection of Lady Zia Wernher in about 1995 ~ sadly all dispersed now I'm told. Still, at least I have the record in the book.
