Karelian Birch (Fabergé egg)

The Karelian Birch egg was considered lost until 2001 when the Moscow collector, Alexander Ivanov, purchased it for his Russian National Museum.

The change was due to austerity measures taken as a result of World War I, both by the Russian Imperial family, and the House of Fabergé.

Its "surprise" was a miniature mechanical elephant, covered with tiny rose-cut diamonds, wound with a small jewel-encrusted key.

[2] The Birch Egg was created in 1917, and was due to be completed and delivered to the Tsar that Easter, as a present for his mother, the Empress Maria Feodorovna.

[1] In 1999 Fabergé's great-granddaughter Tatiana published drawings of the designs for the Birch and Constellation Eggs, but it was assumed that they were both incomplete.
