The Cullinan Diamond has had several owners throughout its extensive history, with King Edward VII as the first owner. Ownership was first transferred to the King because the mine was located in a British colony.

The Cullinan Diamond was then cut into the Cullinan I, Cullinan II, Cullinan III, Cullinan IV, Cullinan V, and Cullinan VI, all of which were inherited by the British royal family. Cullinan V was cut into a custom brooch and became one of Queen Elizabeth II's favorite accessories.
