Exceptional diamonds recovered in 2014 is the subject of this month's
feature article. I have followed industry news reports with interest as these
impressive and unusual diamonds have been dug from deep mines in the African
Exceptional diamonds recovered in 2014 include a few fancy colored diamonds,
and an unusually large white diamond.
As in past years, the Cullinan Diamond Mine in South Africa has produced most
of the notable diamond crystals Mother Nature yielded in 2014.
The Cullinan Diamond Mine was established in 1903 as the Premier Diamond
Mine. It was renamed the Cullinan Diamond Mine in celebration of the mine's 100
year existence. It earned its place in history with the discovery of the
Cullinan diamond in 1905, the largest rough gem diamond ever found at 3,106
Petra Diamonds Ltd acquired the Cullinan mine in 2008. Petra is a diamond
mining group with a diversified portfolio, including ownership interests in
eight producing mines in South Africa and Tanzania, and an exploration
program in Botswana.
As with most South African diamond mines, the
mines a kimberlite pipe (ancient volcano).At the earth's surface, this
kimberlite pipe covered thirty two hectares (one hectare equals
approximately 2.5 acres).
This mine is one of the world's most celebrated diamond mines and is a
source of large, high-quality Type II gem diamonds.
Diamonds occur in nature in two different types…Type I and Type II
Type I diamonds contain nitrogen, and are the more common type found.
Type II diamonds do not contain a measurable amount of nitrogen. Type II
diamonds are usually white, gray, brown, or pink… or very rarely blue,
red, or green.
The occurrence of D color (colorless), internally flawless diamonds in
Type I is known... however, the most sought after diamonds are Type II
Flawless diamonds. Type II diamonds have superior optical properties and
have a superior overall polish to Type I diamonds.
In January, 2014 this press release was issued by Petra:
Recovery of an exceptional 29.6 carat blue diamond
Petra Diamonds Limited announces the recovery of an
exceptional 29.6 carat blue diamond at the Cullinan mine in South Africa.
The stone is an outstanding vivid blue with extraordinary
saturation, tone and clarity, and has the potential to yield a polished stone
of great value and importance.
Blue diamonds are among the rarest and most highly coveted of
all diamonds and the Cullinan mine is the most important source of blues in
the world. This stone is one of the most exceptional stones recovered at
Cullinan during Petra's operation of the mine.
In February, the sale of the 29 carat blue diamond was

carat blue diamond recovered from the Cullinan mine in South Africa in January
has today been sold, following a highly competitive sales process, for
US$25,555,555 (US$862,780 per carat).
The diamond was bought for Cora International NY through the
South African company Golden Yellow Diamonds.
Johan Dippenaar, CEO of Petra, commented:
"This sale result affirms this stone as one of the most
important blue diamonds ever recovered. An additional allure is the diamond's
heritage from the Cullinan mine in South Africa, which is well known as the
source of many of the world's most spectacular diamonds, including the two
main diamonds in the British Crown Jewels, and which is the world's most
important source of very rare blue diamonds."
In June, discovery of another exceptional blue diamond was announced.
Recovery of a 122.52 carat Blue Diamond at Cullinan
Petra Diamonds Limited announces the recovery of an exceptional 122.52 carat
blue diamond at the Cullinan mine in South Africa.

value and upon completion of this process, Petra will be in a position to
evaluate its optimal route to market. The diamond will therefore not be sold
before the end of the Company's current financial year (30 June 2014).
The rarity of a blue diamond of this magnitude sets it apart as a truly
significant find. Cullinan is known as the world's most important source of
blue diamonds and since Petra acquired the mine in 2008, it has continued to
produce a number of exceptional blues
