The Cullinan Dream in the rough.

A 24.18-carat intense blue diamond known as The Cullinan Dream has just sold for $25.4 million at Christie’s Magnificent Jewels auction in New York, breaking all records and becoming the most expensive gem of its kind ever sold at auction.

The diamond, cut from a 122.52-carat rock found at Petra Diamond’s (LON:PDL) Cullinan mine in South Africa in 2014, is the largest of four blue diamonds made from the original.

The Cullinan Dream, a cut-cornered rectangular mixed-cut diamond, has been classified by the Gemological Institute of America as Type IIb. Those kinds of gems are very rare and account for less than one-half of 1% of all diamonds found in nature.

The Cullinan Dream is now a cut-cornered rectangular mixed-cut fancy intense blue diamond, weighing approximately 24.18 carats.

Type IIb gems contain a small amount of the element boron trapped in the crystal carbon structure during their formation that can give rise to a blue or grey coloration, Petra Diamonds said in a statement.

The mine is best known for the discovery of the Cullinan diamond, at 3,106 carats the largest rough diamond ever found. The gem was cut into two highly significant diamonds, which can be found in the British Crown Jewels.

It is flanked on either side by a tapered baguette-cut diamond and set in a platinum ring, inscribed “Cullinan Dream”.

Since acquiring a majority stake in the mine in 2008, Petra Diamonds has found some high-profile blue diamonds, including “The Blue Moon of Josephine,” which sold in November for $48.5 million and “The Star of Josephine” — a 7.03 carat polished stone that sold in 2009 for $9.49 million, representing what at the time was a world record price per carat of $1.35 million.

Russia’s Alrosa (MCX:ALRS), the world’s top diamond producer by output in carats, has unveiled the discovery of a 241.21-carat rough diamond at its Nyurbinsky open-pit mine.

The diamond is one of the largest ever recovered in Russia.

The precious rock, said the company, is one of the largest rough diamonds ever recovered in Russia and the third largest among those found by the company’s Nyurba Mining and Processing Division.

The massive diamond measures 38.64 mm by 27.34 mm by 25.46 mm, and is translucent with a grey hue. Traces of dissolution–etching channels and caverns–are observed on the surface.

The intermediate and peripheral zones have large cracks and the crystal contains graphite and sulphide inclusions, Alrosa said.

The Nyurbinsky has been in operations since 2001. Identified reserves January last year amounted to 36.9 million carats.

The Nyurba Mining and Processing Division is one of Alrosa’s youngest divisions, in charge of the Nakyn ore field as well as the Nyurbinsky and Botuobinsky open-pit mines.

The state-owned diamond miner may be privatized as soon as this summer, Russian Economy Minister Alexei Ulyukayev said at the St Petersburg International Economic Forum on Thursday, according to Reuters.
