ST. PETERSBURG, Russia (AFP) ― Russian billionaire Viktor Vekselberg on Tuesday opened a museum to display his glittering collection of Faberge eggs, once owned by the tsars, in the former imperial capital of Saint Petersburg.

The new Faberge Museum located in the Shuvalov Palace in the city centre put on display nine of the eggs, once given as Easter gifts by the royal family, as well as thousands of jewelled objets d’art from icons to cigar cases.

Vekselberg bought the collection of eggs from the estate of the late Malcolm Forbes, the U.S. publisher of Forbes magazine in 2004, vowing to bring them back to Russia.

“We started this project more than 10 years ago, and we are happy to present the result to you,” Vekselberg said at the opening.

The jewelled eggs with enamel and painted details include one given by the last tsar Nicholas II to his mother, Maria Fyodorovna, which is decorated with his portrait as well as that of his heir, Alexei.

Another made to celebrate the first anniversary of Nicholas II’s coronation has a surprise inside: a model of a tiny gold carriage. Others contain a gold hen and an enamelled rosebud.

The 18th-century mansion housing the museum originally belonged to Ivan Shuvalov, a favorite of Tsarina Elizabeth Petrovna. It was used for welcoming international delegations in Soviet days.

“The inauguration of this museum is a great event for all of Russia,” said Culture Minister Vladimir Medinsky at the opening. “Now we have the chance to see this beautiful and precious collection in Saint Petersburg.”

He stressed that the museum was entirely privately funded.

“Not a single kopeck was spent from the Russian budget.”
