A First Sold Diamond Febergé that once belonged to the Russian Family sold for a record £22.9m ($30.2m) in London.
The winter egg – considered one of the most beautiful creations of the Jewendary Jeweler – was bought by an anonymous bidder on Tuesday, Christie House said.
It is decorated with 4,500 diamonds commissioned by Tsar Nicholas II in 1913 as a gift to his mother.
The previous record for a Fabergé egg was £8.9M paid at auction in 2007.
“Today’s result sets a new world auction record for a work by Fabergé, reinforcing the enduring significance of this masterpiece,” Margo Oganesian was quoted as saying by AFP News Agency.
The 8.2cm High (3.2in) egg was made by Carl Fabergé, based on a design by Alma Theresia Pihl, one of only two female workmasters of the St Petersburg Company.
It is carved from crystal stone and decorated with rose cut diamonds, as well as platinum snowflake Motifs.
The egg opens to reveal a small basket of white quartz flowers inside.
Falergé House produced 50 eggs for Russia’s Imperial Romanov Family, and the imperial winter egg is one of only seven left in private hands.
Some are lost or owned by institutions or museums.
The eggs were produced from 1885 until Tsar Nicholas II was forced to abdicate in 1917.
