Winter Egg, by Theo Faberge, 1986.
Made of cobalt blue and clear crystal, it is set with the Imperial Crown
of Russia. Delicate bows and holly decorate the Egg, which opens to
reveal a music box that plays ‘Silent Night’. The sterling silver base
is engine turned in a starburst pattern. The vermeil crown inside winds
up the mechanism and turns with the music. A cabochon ruby operates the
miniature mechanism.
