It is currently held in the Kremlin Armoury Museum in Moscow, and it is one of the few imperial Fabergé eggs that were never sold after the Russian Revolution.
The Standart Yacht Leaf Egg is a transparent hollowed-out rock crystal egg, mounted horizontally, with a gold band with inlaid leaves of green enamel and small diamonds marking the separation point between upper and lower halves, which bears the inscription "Standart 1909".
A crowned lapis lazuli eagle is perched on either side of the egg and a large pear-shaped pearl hangs from each.
Outfitted with ornate fixtures, including mahogany paneling, crystal chandeliers, and other amenities (including a stable with a cow to provide the imperial children with fresh milk) it was a floating palace for the Russian Imperial Family for their vacations in the Baltic Sea.
The Russian Imperial Family was vacationing on the Standart during the summer of 1914, when they received the news of the assassination of Archduke Franz Ferdinand, in Sarajevo, marking the start of World War I.
