The Imperial St. Petersburg.
St. Petersburg is presented in an elaborate multi-layer white translucent enamel Egg of the Tsars decorated with 4.25 carats of diamonds. The diamonds have been employed in recreating legendary symbols of St. Petersburg. The Admiralty Spire, the Rostral Columns, the Arch of the General Staff Building and the famous drawbridges that open at night to allow for passage of large vessels can be seen picked-out in diamonds. Ulysse Nardin's anchor serves to link the egg to the white marble base.
