On Tuesday, November 19, Russian billionaire Viktor Vekselberg opened a museum to display his remarkable collection of Faberge eggs, once owned by the Tsars, in Saint Petersburg. Vekselberg purchased the collection from the estate of the late Malcolm Forbes, the publisher of Forbes magazine, in 2004.

Vekselberg’s collection of Faberge objects is rates as one of the world’s most valuable and was previously valued at $90 million. The museum, which was entirely privately funded, will open to the public in December 2013.
