Cullinan produced 9 major stones totalling , plus 96 minor
brilliants and some unpolished fragments weighing . All but the two largest stones – Cullinans I and II – remained in Amsterdam by arrangement as the fee for Asscher's services, Cullinans I and II are part of the Crown Jewels, The South African government also bought the minor brilliants from Asscher and distributed them to Queen Mary;
Louis Botha, the then prime minister of South Africa; the diamond merchants Arthur and Alexander Levy, who supervised the cutting of Cullinan; and Jacob Romijn (later Romyn), who co-founded the first
trade union in the diamond industry. Some were set by Mary into a long platinum chain, which Elizabeth II never wore in public, saying that "it gets in the soup". In the 1960s, two minor Cullinan diamonds owned by Louis Botha's heirs were analysed at the
De Beers laboratory in Johannesburg and found to be completely free of
nitrogen or any other impurities. Cullinans I and II were examined in the 1980s by gemologists at the
Tower of London and both graded as colourless
type IIa.
Cullinan I Cullinan I, or the Great Star of Africa, is a
pendeloque cut brilliant weighing and has 74 facets. It is set at the top of the
Sovereign's Sceptre with Cross, made in 1661, which had to be redesigned in 1910 to accommodate it. Cullinan I was surpassed as the world's largest cut diamond by the brown
Golden Jubilee Diamond in 1992, which was surpassed in 2025 by the
Black falcon. Cullinan I remains the largest colourless cut diamond in the world. In terms of clarity, it has a few tiny cleavages and a small patch of graining. The diamond is fitted with loops and can be taken out of its setting to be worn as a pendant suspended from Cullinan II to make a
brooch. Queen Mary, wife of George V, often wore it like this. In 1908, the stone was valued at US$2.5 million (equivalent to US$ million in ) – two and a half times the rough Cullinan's estimated value.
Cullinan II Cullinan II, or the Second Star of Africa, is a cushion-cut brilliant with 66 facets weighing set in the front of the
Imperial State Crown, It measures . The diamond has a number of tiny flaws, scratches on the table facet, and a small chip at the girdle. Like Cullinan I, it is held in place by a yellow gold enclosure, which is screwed onto the crown. In 1912 the
Delhi Durbar Tiara, worn the previous year by Mary instead of a crown at the
Delhi Durbar, where her husband wore the
Imperial Crown of India, was also adapted to take Cullinans III and IV. Elizabeth II frequently wore Cullinan III in combination with Cullinan IV as a brooch. In total, the brooch is long and wide. Cullinan III has also been used as a pendant on the
Coronation Necklace, where it occasionally replaced the Lahore Diamond.

Koh-i-Noor Cullinan IV, also referred to as a Lesser Star of Africa, is square-cut and weighs .
Cullinan V Cullinan V is an heart-shaped diamond set in the centre of a platinum brooch that formed a part of the
stomacher made for Queen Mary to wear at the Delhi Durbar in 1911. The brooch was designed to show off Cullinan V and is pavé-set with a border of smaller diamonds. It can be suspended from the VIII brooch and can be used to suspend the VII pendant. It was often worn like this by Mary.
