Anichkov Palace
The Sapphire Pendant Egg was sent to Tsar Alexander III on April 5, 1886 from Fabergé's workshop. The egg was presented by the Tsar to Tsarina Marie Fedorovna on April 13 of the same year. The egg was housed in the Anichkov Palace until the Revolution. The last documented location of the egg is from the archive of the provisional government's inventory in 1922 when the egg was held in the Armory Palace of the Kremlin. It is not known whether the egg was lost or is currently in private hands.
