Koh-I-Noor
The Koh-I-Noor is a 105.602 carats weighing oval cut
diamond. The weight of the rough-diamond is estimated at 600 carats. The
stone is set in the Maltese Cross at the front of the crown made for Queen
Elizabeth the Queen Mother with more than two thousand other diamonds. “Koh
I Noor” comes from the Persian language and means “Mountain of Light”. It is
regarded as one of the most famous diamonds in history.
Its origin is in the subcontinent of India and it
belonged to various Indian and Persian rulers at different points in
history. The diamond was first described in 1304 when it was held by the
Rajah of Malwa, India. Later it fell into the hands of the Sultan Baber.
During the next two centuries, the diamond was one of the
precious jewels of the Mogul Emperors. 1739 Nadir Shah of Persia invaded
Dehli, India and pillaged the city to acquire the great diamond but failed.
The legend says one of the harem women informed Nadir Shah that the jewel
was kept hidden by Mohammed Shah in his turban. Taking advantage of an
Oriental custom, Nadir suggested to exchange turbans at the victory
celebration. This is a well-known oriental custom signifying the creation of
brotherly ties, sincerity and eternal friendship. Mohammed Shah was
astonished at his quick-thinking rival but he was hardly in a position to
resist such a request. So he accepted. Later that night, when Nadir Shah had
gone to his appartement for the night, he unfolded the host's turban and
found the diamond. When he set his eyes on this beautiful gem he exclaimed:
“Koh-i-noor”, meaning “Mountain of Light.” The famous diamond now had a
name. Nadir Shah carried off the Koh-i-noor to Persia in 1739.
In 1747 Nadir Shah was murdered and the diamond came into
the hands of Ahmad Shah of Afghanistan until it was taken by the Sikh
Maharaja (King) of Punjab Ranjit Singh, during a campaign in Afghanistan in
1813. Later Ranjit Singh crowned himself as the ruler of Punjab. On his
deathbed in 1839 he willed the Koh-i-noor to a Hindu temple in Orissa. But
after his death the British administrators did not execute his will and
Ranjit Singh’s successor gave the diamond to Queen Victoria in 1851.
Because of the lack of brilliance in the stone it was
decided to re-cut the diamond to increase its brilliance. The Koh-I-Noor was
reduced from 186 carats to its present size of 105.602 carats.
In 1936 the diamond was set into the crown of the new
Queen Elizabeth, wife of King George VI. The crown rested atop her coffin in
2002.
The government of India started some question to the
British Government for the return of this diamond, claiming legitimate
ownership. Until today the gem remains in the United Kingdom.
Mostly the weight of the Koh-I-Noor is published with
108,93 carats. But in 1988 during the maintenance and cleaning of the crown
by the Crown Jeweller Mr. Bill Summers the opportunity was taken to remove
the diamond. It was weighed in the presences of witnesses on a modern
certified electronic balance. The measurements are 36.00 × 31.90 × 13.04 mm.
The Excelsior
The Excelsior which means "higher" This
large diamond weighing 995,2 carats was found on the evening of June 30th,
1893 by an African mine worker. He picked it up in a shovel of gravel which
he was loading into a truck. The diamond was discovered in the Jagersfontein
mine in the Orange River Colony. It is not only one of the worlds largest
diamonds it is the second largest diamond ever found. It is about one third
the size of the Cullinan. It originally weighed 995.2 carats. The diamond
was cut into ten pieces, the three largest weighing 158, 147 and 130 carats.
These pieces were then cut into 21 gems ranging from 70 carats to less than
1 carat. An African mine worker found the diamond as he was loading his
truck, he kept the find secret until he could safely turn it over to the
mine manager who rewarded him with some money, a horse and a saddle.
After prolonged study it was decided to first
cleave the diamond into ten pieces: this operation which was performed by
Mr. A. Asscher, resulting in the three largest pieces weighing 158, 147 and
130 carats. The polishing was supervised by Henry Koe and yielded 21 gems,
ranging from 70 carats to less than 1 carat. They totalled 373.75 carats
which represented a loss in weight of almost 63 percent. The final result,
however, was considered to have been better than anyone had expected. The
specifications of the larger gems cut from the Excelsior are as follows:
(metric carats)
Excelsior I ... 69.68 carats ... pear shape
Excelsior II ... 47.03 carats ... pear shape
Excelsior III ... 46.90 carats ... pear shape (the Rovensky?)
Excelsior IV ... 40.23 carats ... marquise
Excelsior V ... 34.91 carats ... pear shape
Excelsior VI ... 28.61 carats ... marquise
Excelsior VII ... 26.30 carats ... marquise
Excelsior VIII ... 24.31 carats ... pear shape
Excelsior IX ... 16.78 carats ... pear shape
Excelsior X ... 13.86 carats ... pear shape
Excelsior XI ... 9.82 carats ... pear shape
The Excelsior gems were sold seperately, three of
them were bought by Tiffany & Co., in their old store in Union Square in New
York City. The names of the other buyers have not been disclosed but it is
known that De Beers displayed one of the marquise-shaped fragments at the
1939 World's Fair in New York.

The Millennium Star
In 1990 the diamond was discovered in the Mbuji-Mayi district of Zaire
(Republic of the Congo) in alluvial deposits and was purchased by De Beers.
The cutters of the Steinmetz Diamonds Group took over three years to
complete the classic pear form with 54 facets. Some 100 plastic models of
the original rough were made, and these were almost all used to plan and
design the optimum polished stone in beauty and weight. The cutting was done
using lasers. The Millennium Star is a pear-shaped diamond weighing 204,04
carats. It is the world’s second largest diamond in the top colour-grade D,
internally and externally flawless, cut to perfect proportions. The rough
diamond was weighing the magic number of 777 carats. The first is the 273.15
carat Centenary Diamond. The first display to public was in October 1999 as
the centerpiece of the “De Beers Millennium Diamond Collection” in London. A
second exhibition was the “De Beers Millennium Jewels Exhibition” at the new
Millennium Dome in London in 2000. There was an attempt to steal the diamond
from the exhibition hall by using bulldozers to break in but the attempt was
thwarted by a tip to Scotland Yard.
