In 1913, Agathon Fabergé, son of Peter Carl Fabergé of the House of Fabergé, the crown jewellers, recommended that the Imperial regalia be re-catalogued and overhauled. The tsar gave his approval and by July 1914, work on the Imperial orb and sceptre had been completed, and work was about to commence on the crowns. Rising tensions and the outbreak of the First World War put a stop to further work, and the regalia items were loaded into nine strong-boxes and sent from Saint Petersburg to Moscow for safekeeping. They were stored in the Kremlin Armoury. The crown remained there with the rest of the regalia during and after the February and October Revolutions in 1917.
