| The Kremlin's Diamond Depository dates back to the reign of Peter I, who decreed for the most valuable treasures to become property of the Russian state, not only of the Royal Family. From then on, precious regalia, insignia and secular jewelry belonging to several generations of Russian rulers would be stored in the Diamond Room in St. Petersburg.|
When WWI broke out, the collection was moved to Moscow and placed in the Armory basement, where it would stay for nearly 8 years. The Diamond Depository was established in 1922.
In 1967, when the Soviet state was celebrating its 50th anniversary the treasures were placed on public display.
