Banded in diamonds and translucent emerald enamel, it is surmounted by a rare Siberian emerald weighing 26 karats, cut en cabochon and pointed. On a plinth of rock crystal, the double spheroid base in contrastyly colorful enamels, twice circled with diamonds, is designed with monograms of the Tsarina, as the Princess Alix of Hesse-Darmstadt, before her marriage, and later as Aleksandra Feodorovna, Empress of Russia. Above these appears a series of diamond crowns of the respective royal houses.

The two halves of this rock crystal egg are held together by a narrow rose-cut diamond and translucent emerald-green enameled gold mount, culminating at the top with a 27 carat cabochon Siberian emerald, probably the biggest gem used in the Tsar Imperial Easter Eggs.

The Egg is supported on a circular rock crystal plinth. The monograms of the Tsarina as the Princess Alex of Hesse-Darmstadt before her marriage, and as Alexandra Fyodorovna, Tsarina of Russia, each surmounted by their respective crown, appear as separate formal patterns encircling this plinth.

This was the last of the five Imperial Easter Eggs bought by Lillian Thomas Pratt. The other four Eggs are the 1898 Pelican Egg, the 1903 Peter the Great Egg, the 1912 Tsarevich Egg and the 1915 Red Cross Portraits Egg.

In 1930 one of the ten Eggs sold by the Antikvariat to the Hammer Galleries in New York. Ca. 1945 bought by Lillian Thomas Pratt, wife of a General Motors executive. 1947 Collection of the late Lillian Thomas Pratt, willed to Virginia Museum of Fine Arts, Richmond, USA.

Its "surprise" is that the emerald at the apex, when depressed, engages a hook that revolves the miniatures on a columnar axis. All but two miniatures are signed by Johannes Zehngraf (1857-1908), and are framed in gold.
