1907 - King Edward VII was presented with the Cullinan Diamond at Sandringham House by Agent-General of South Africa, Sir Richard Solomon. The original (whole) Cullinan was sold to the Transvaal government, which presented it to Edward VII on his 66th birthday on this day in 1907. The whole diamond was studied for months before it was cut to ensure the best possible outcome. It was eventually cut into 3 principal sections which in turn ended up producing nine major gems, 96 smaller brilliants, and 9.50 carats of unpolished pieces.

Cullinan I, aka The Great Star of Africa, pendeloque-cut brilliant weighing 530.2 carats and contains 74 facets is set at the top of the Sovereign's Sceptre with Cross which had to be redesigned in 1910 to accommodate it.

Cullinan II aka The Second Star of Africa, is a cushion-cut brilliant with 66 facets weighing 317.4 carats which is set in the front of the Imperial State Crown, below the Black Prince's Ruby. measures 4.54 cm × 4.08 cm × 2.42 cm

Cullinan III aka The Lesser Star of Africa, is pear-cut and weighs 94.4 carats. In 1911, HM Queen Mary, The Queen Consort had it set in the top cross pattée of a crown that she personally bought for her coronation. In 1914, Cullinan III was permanently replaced on the crown by a crystal model. Today, it is most frequently worn in combination with Cullinan IV by Elizabeth II as a brooch. In total, the brooch is 6.5 cm long and 2.4 cm wide.

Cullinan IV is also referred to as a Lesser Star of Africa, is square-cut and weighs 63.6 carats. It was also set in the base of Queen Mary's Crown but was removed in 1914.

Cullinan V is an 18.8-carat heart-shaped diamond set in the center 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 Queen Mary.

Cullinan VI is a marquise-cut and weighs 11.5 carats. It hangs from the brooch containing
Cullinan VIII and forming part of the stomacher of the Delhi Durbar parure.

Cullinan VIII is an oblong-cut diamond weighing 6.8 carats. It is set in the center of a brooch forming part of the stomacher of the Delhi Durbar parure. Together with Cullinan VI it forms a brooch. (Out of order because Cullinan VI & VIII are set together)

Cullinan VII is also marquise-cut and weighs 8.8 carats. It was originally given by Edward VII to his wife and consort Queen Alexandra. After his death she gave the jewel to Queen Mary, who had it set as a pendant hanging from the diamond-and-emerald Delhi Durbar necklace, part of the parure.

Cullinan IX is the smallest of the principal diamonds to be obtained from the rough Cullinan. It is a pendeloque or stepped pear-cut stone, weighs 4.39 carats and is set in a platinum ring known as the Cullinan IX Ring.
