1907

The Cullinan diamond is discovered. At 3,106 carats it is a legendary find which achieves instant notoriety across the globe. The diamond is presented to Great Britain's King Edward VII, and he invites the Asscher brothers to London to discuss cleaving the diamond. It is decided that Joseph Asscher will cut the Cullinan into three parts, necessary because of the inclusions within the rough diamond.

1908

On a cold February day a noteable audience gathers to watch Joseph Asscher cleave the natural wonder. He needs to hit the Cullinan in exactly the right place... He strikes the diamond , but the blade breaks, not the stone. He dismisses all present and remarks that the largest diamond ever found seems to require significantly larger tools!

The following week, armed with new tools Joseph Asscher resumes his work, allowing nobody but the notary public in the room. Although later, urban legend recounts that Joseph Asscher faints after striking the diamond with a tremendous blow, in truth he remains entirely focused, demonstrating unprecedented expert force as he hits the Cullinan in exactly the right place, the stone, the stone is cleft according to his original calculations. He pauses, crouches to examine his work, then rushes into the next room and lets out a relieved cheer; the champagne corks pop. Later, the Cullinan diamonds are polished, ready to take pride of place in Great Britain's Crown Jewels.

The two largest pieces cut, The Greater and Lesser Star of Africa, were kept by King Edward VII and the rest was left with the Asscher Company as payment for cutting the diamond. Later, the Asscher Company sold the larger pieces to the Transvaal Government who in turn gave them to Queen Mary (the daughter-in-law of King Edward) as a sign of their devotion to the British Crown. She had the diamonds set in her own pieces of jewellery and bequeathed the 7 remaining original Cullinan diamonds to Queen Elizabeth II in 1953.

These are the final polished diamonds as originally cut by Joseph Asscher in 1907.

Cullinan VI and VII

The Cullinan VI diamond is marquise cut and weighs 11.5 carats. King Edward VII had given to his queen consort, HM Queen Alexandra, who had it set into her Regal Circlet in 1908.

Currently, it is set into a brooch and suspends from another diamond cut from the Cullinan rough, Cullinan VIII.

This diamond is often confused with Cullinan VII as they are both marquise cut. The difference between the two stones is that Cullinan VI is a longer, more pointed style of marquise cut, and the Cullinan VII is slightly smaller and more rounded marquise cut.

This photo shows the difference in shape and size from the Cullinan VI and VII respectively.

The Cullinan VII weighs 8.8 carats and was placed in a necklace along with cabochon emeralds and presented to HM Queen Mary by the Maharanee of Patiala on behalf of the ladies of India to mark the first visit to India by a British Queen-Empress. Queen Mary had the necklace altered to match her Delhi Durbar Parure. Both the emerald and diamond drops are detachable.

Cullinan V

The fifth stone cut from the Cullinan rough diamond is a heart shaped diamond weighing 18.8 carats. It was given to Queen Mary by the government of South Africa in 1910. She had it set in a platinum and diamond brooch, but also gave it a dual purpose.

The diamond was detachable from the brooch and could be placed as the centre diamond in the Delhi Durbar Emerald and Diamond Stomacher, made in 1911.

The brooch is now personally owned by HM Queen Elizabeth II and does not belong to the Crown Jewels.

This photograph shows Queen Mary wearing the Delhi Durbar Parure (the set including the necklace, earrings and stomacher) including the Cullinan V.

Look closely at the picture and you will see the Cullinan IV in the centre of the Queen's coronet.

Cullinan II - The Lesser Star of Africa

The Cullinan II, also known as The Lesser Star of Africa, was the second largest stone cut from the Cullinan Rough diamond. It weighs 317 carats and is cushion cut.








It is currently mounted in the Imperial State Crown of Great Britain along with 2,867 other diamonds, 273 pearls, 17 sapphires, 11 emeralds and 5 rubies. The Cullinan II holds one of the places of honour, located in the front of the crown, at the centre just above the ermine band.

Cullinan I - The Star of Africa

The largest diamond cut from the Cullinan rough was the Cullinan I, also known as The Star of Africa. It is a pear shaped diamond weighing 530.2 carats with 74 facets. It was known as the largest cut diamond in the world until the 1985 discovery of the Golden Jubilee Diamond (545 carats), also from the Premier Mine in South Africa.

The Cullinan I is mounted in the Sovreign's Sceptre and housed in the Tower of London with the other Crown Jewels. It is the largest colourless cut diamond with no inclusions (flawless) in the world today.

It measures approximately 2" long, 1.7" wide is similar in size to a hen's egg.

It is valued today at £200 million or $400 million.
