Cullinan produced 9 major stones of 1,055.89 carats (211.178 g) in total, and 96 minor brilliants weighing 7.55 carats (1.510 g) (on average, 0.079 carats each) -- a yield from the rough stone of 34.25 per cent. There are also 9.5 carats (1.90 g) of unpolished fragments. All but the two largest stones -- Cullinans I and II -- remained in Amsterdam by arrangement as the fee for Asscher 's services, until the South African government bought them (except Cullinan VI, which Edward VII had purchased and given to his wife Queen Alexandra in 1907), and the High Commissioner for Southern Africa presented them to Queen Mary on 28 June 1910. Mary also inherited Cullinan VI from Alexandra, and she left all of her Cullinan diamonds to her granddaughter Queen Elizabeth II in 1953. Cullinans I and II are part of the Crown Jewels, which belong to the Queen in right of the Crown. Asscher sold the minor stones to various buyers, including then prime minister of South Africa, Louis Botha, and the diamond merchants Arthur and Alexander Levy, who supervised the cutting of Cullinan. Some were purchased by Mary and set in a long platinum chain, which Elizabeth has never worn in public, saying that "it gets in the soup ''.
