Egg is lost. It is possible that a surprise from Nephrite Faberge's Egg it was shown in London in 1935. The exhibition catalog mentions "Alexander's III miniature in a frame from the nephrite, Great Duchess Xenia provided by her Imperial Majesty from Russia". Unfortunately no images remained.
Will pay the attention to others, eggs gifts of the emperor, Egg the Clover and the most beautiful Swan Egg.
