Crystal gains access to exclusives at Fabergé MuseumCrystal gains access to exclusives at Fabergé Museum

Precious bejeweled Fabergé eggs are the centerpiece of the 'insider' tour, although more than 4,000 antique pieces of Russian decorative arts and palatial surroundings will envelop participants in opulence during their visit.

The museum curator will guide Crystal passengers through Russian billionaire Viktor Vekselberg's private collection of imperial Fabergé, which includes 15 of the world's remaining 50 eggs designed by Carl Fabergé. Nine of them belonged to Russia's final tsarist family, the Romanovs, and Crystal said they are considered to be the jeweler's finest works.

The new boutique excursion is available for $229 with four Crystal Symphony 10-day voyages from Stockholm and Copenhagen, departing June 24, July 4, July 28 and Aug. 7. Passengers who explore St. Petersburg with an organized excursion avoid the need for a visa within the city.
