Origin of name
The Cullinan diamond discovered accidentally in the
Premier diamond mines of Transvaal, South Africa, on January 26th, 1905, had
an enormous weight of 3,106 carats, making it the largest ever gem-quality
rough diamond to be discovered in the world. The diamond was named after Sir
Thomas Cullinan, the discoverer and owner of the Premier diamond mines,
where mining activity began just three years before the record-breaking
discovery.
Characteristics of the
diamond
The cutters of the Cullinan diamond, I. J. Asscher & Co.
of Amsterdam, cleaved the enormous rough diamond into 9 large pieces and
around 100 other smaller pieces, all of which were eventually cut and
polished into different shapes and sizes of diamonds. The Characteristics of
the 9 large diamonds are summarized in the table below.

When the cutting of the Cullinan diamond was completed in
1908, the Cullinan I also known as the Greater Star of Africa with a weight
of 530.20 carats became the largest faceted diamond in the world. The
Cullinan I held this rare distinction for a period of about 80 years, until
the discovery of the 755-carat Golden Jubilee rough diamond in 1985, which
was subsequently transformed into the 545.67-carat, cushion-shaped, fancy
yellow brown diamond, the largest faceted diamond in the world.
Other notable distinctions held by the Cullinan I
diamond are the largest pear-shape faceted diamond in the world; the largest
D-color faceted diamond in the world; and the largest D-color, pear-shaped,
faceted diamond in the world. See table below, and rank order of famous

History
The Cullinan diamond was discovered accidentally on
January 26th, 1905, by the surface manager of the Premier diamond mines in
Transvaal, South Africa, Mr. Frederick Wells, when he was on a routine
inspection of the mine, late afternoon, on that particular day. Mr. Wells
was about 18ft below the surface of the earth, when his attention was drawn
by a shining object reflecting the last inclined rays of the setting sun, on
the steep wall of the mine, a few feet above his head. Mr. Wells lost no
time in scaling the wall and retrieving the shining object, which at first
glance appeared to be a large diamond crystal. The object was immediately
taken for testing, and eventually turned out to be the largest gem-quality
rough diamond ever discovered, weighing 3,106 carats. This unique
distinction was previously held by the 995-carat Excelsior diamond for a
period of 12 years, from 1893 to 1905. The Cullinan diamond turned out to be
the undisputed King of all rough diamonds in the history of mankind, and had
been holding this position for the last 102 years. It is highly unlikely
that any rival could appear, that could challenge the exalted position held
by the Cullinan, in the future, unless new deposits of diamond are
discovered in the world. See table below.

The Premier diamond mine was discovered in the year 1902,
by Sir Thomas Cullinan. The massive Cullinan diamond was discovered just
three years after this, and this accidental and record-breaking discovery
provided a much needed boost for further mining activity. In fact many
diamond experts believed that the Cullinan was only a fragment of perhaps a
larger diamond, and the remaining larger piece still awaited discovery. The
prospect of finding the larger portion of the Cullinan stimulated the
activities of miners and prospectors.
The Cullinan was purchased by the Transvaal Government,
and presented to the reigning British Monarch, King Edward VII, to mark the
occasion of his 66th birthday, which fell on November 9th, 1907. In the
early 20th century transport of passengers and mail was mainly by ship, and
as such transporting the priceless diamond to England, raised serious
security concerns. An ingenuous plan was put in place that required the
boarding by detectives of a London-bound steamer, purported to be carrying
the Cullinan diamond. But this was only a diversionary tactic. In fact the
stone on the ship was only a fake, meant for any daring thief. The actual
diamond however, was sent to England in a plain box, via parcel post.
King Edward commissioned the renowned diamond cutters of
Amsterdam I. J. Asscher & Co. - who introduced a new diamond cut in 1902
called the Asscher-cut, also known as the square emerald-cut - to undertake
the difficult task of cutting the Cullinan. The company had achieved
credibility by cutting the Excelsior diamond in 1904, the world's largest
un-cut diamond, before the discovery of the Cullinan diamond in 1905.
The stone was subjected to careful examination before the
actual cutting. One of those who examined the Cullinan was Sir. William
Crookes, who was astounded by it's remarkable clarity, but at the same time
reported of a black spot in the midddle, around which the colors were very
vivid, and changed as the analyzer was turned. This phenomenon according to
Sir Williams was caused by severe internal strain, which is not uncommon for
diamonds. Instances have been reported when diamonds have exploded when
reaching the surface or sometimes in the pockets of miners due to body
warmth, all attributed to internal strain.
The cutting of the Cullinan began on February 10th, 1908.
The diamond was first cleaved along a pre-planned axis, by Mr. Asscher
himself, who initially made an incision about half an inch deep. to
accommodate the blade of a specially designed knife, which was followed by a
heavy blow on the knife. The diamond split into two sections as expected.
this was followed by a second cleavage in the same direction, producing
three principal sections. Each of the sections were subjected to further
cleavage, producing altogether nine large pieces. Around a 100 other smaller
pieces were also produced. Faceting and polishing of the pieces then began,
the shape of the cut being decided according to the dimensions of each
piece. When the whole process was finally completed, there were nine major
gems, and 96 smaller brilliants.
The nine larger Cullinan diamonds are an important
component of the British Crown Jewels and some of them are on display at the
Tower of London, with the other Crown Jewels.
Cullinan
I
The Cullinan I, aka the Greater Star of Africa , is the
largest of the Cullinan diamonds, with a pear-shaped cut and weighing 530.20
carats. This was the largest faceted diamond in the world, until the
discovery of the Golden Jubilee diamond, also from the premier mine in 1985.
However, it still remains the largest, D-color, faceted diamond in the
world.
The dimensions of the diamond are 58.9 x 45.4 x 27.7 mm. The stone has a
total of 76 facets. On the orders of King Edward VII, the Cullinan I was
mounted on the head of the Royal Scepter, and it is now on display in the
Tower of London.
Cullinan II
The Cullinan II, aka the lesser Star of Africa is the
second largest Cullinan diamond, with a cushion shape, weighing 317.4
carats. It is the fourth largest faceted diamond, and the second largest,
D-color, faceted diamond in the world, and is also
part of the British Crown Jewels. It has been mounted on the brow or band of
the Imperial State Crown of Great Britain, which also features other notable
precious stones such as St. Edwards Sapphire, the Stuart Sapphire and the
Black Princess Ruby. It is also on display in the Tower of London, with the
other Crown Jewels.
Cullinan III
The Cullinan III weighing 94.40 carats has a pear-shaped
cut and is mounted in the finial of Queen Mary's (Queen consort of King
George V) Crown, but when required Cullinan III could be combined with
Cullinan IV to form a pendant-brooch, and most of Queen Mary's portraits
show her wearing this combination. Queen Elizabeth II, the present British
Monarch, also uses the two diamonds in the same way.
Cullinan IV
The Cullinan IV, with a cushion-cut weighs 63.60 carats,
and like the Cullinan III was originally mounted on Queen Mary's Crown, but
as stated above, can also be worn as a jewelry.
Cullinan V
The Cullinan V, with a triangular pear-cut, weighs 18.80
carats, and also had a dual use, one as a piece of jewelry, mounted in a
brooch for Queen Mary and the other to be worn in the circlet of her crown,
as a replacement for the Koh-i-Noor. This was after the Koh-i-Noor was
removed to be mounted on a new crown for Elizabeth (Queen Mother), the
Duchess of York after her husband George VI's accession to the throne, upon
the abdication of Edward VIII, on December 11, 1936.
Cullinan VI
The Cullinan VI is a marquise-cut stone, with a weight of
11.50 carats. King Edward VII presented it to his Queen consort, Queen
Alexandra. This diamond is now worn by Queen Elizabeth II, as a drop on a
diamond and emerald necklace. It is said that the Cullinan VI was the
section of the Cullinan that was worn more frequently as a jewelry by the
young Queen Elizabeth, than any other section of the Cullinan.
Cullinan VII and VIII
The Cullinan VII is also a marquise-cut stone, weighing
8.80 carats, mounted as a pendant on an all diamond brooch, in the center of
which is the 6.80 carat, cushion-cut Cullinan VIII.
Cullinan IX
The Cullinan IX is the smallest of the Cullinan diamonds,
weighing only 4.39 carats and cut in a pear shape. The diamond was mounted
in a ring , with a prong setting for Queen Mary, Queen consort of King
George V. This ring is also sometimes worn by Queen Elizabeth II.
