The Fabergé company made several pieces for private clients (about 15 are known). Among them, there is a series of seven eggs given to his wife by the millionaire owner of Siberian gold and platinum mines, Alexander Ferdynandowicz Kelch. The eight eggs were made by Fabergé at the request of Felix Yusupov, Alfred Nobel's nephew, the Rothschilds, the Duchess of Marlborough, and several unidentified people.
They are not original, they often contain elements previously used in Imperial eggs. It is believed that some Easter eggs made for private individuals were never documented.
