The Darya-i-Nur Pink Diamond

0
The Darya-i-Nur Pink Diamond of the Iranian Crown Jewels

The Darya-i-Nur, which means “Ocean of Light” in Persian, is one of the largest and most celebrated diamonds in the world, weighing an estimated 186 carats. Its color, pale pink, is one of the rarest to be found in diamonds. The Darya-i-Nur presently forms part of the Iranian Crown Jewels and is on display at the Central Bank of Iran in Tehran.

This diamond, like the Koh-i-Noor (read here), was mined at the Golconda mines in Andhra Pradesh.  It found its way into the possession of the Mughal Emperors.

In 1739, Nader Shah of Persia invaded Northern India, occupied Delhi and then massacred many of its inhabitants. As payment for returning the crown of India to the Mughal emperor, Muhammad, he took possession of the entire fabled treasury of the Mughals, including the Darya-i-Nur, in addition to the Koh-i-Noor and the Peacock Throne. All of these treasures were carried to Iran by Nader Shah and the Darya-i-Nur has remained there ever since.

The Coronation of The Shah of Iran

Reza Shah, founder of the Pahlavi Dynasty, wore the diamond as a decoration on his military hat during his coronation in 1926, and it was used again by his son Mohammad Reza Shah Pahlavi’s (the last of the Shah of Iran) coronation ceremony in 1967.

The Nur-ul-Ain Pink Diamond Mounted On A Tiara

In 1965, a Canadian team conducting research on the Iranian Crown Jewels concluded that the Darya-i-Nur may well have been part of a large pink diamond that had been studded in the throne of the Mughal Emperor Shah Jahan. This diamond may have been cut into two pieces; the larger part is the Darya-i-Nur, the smaller part is believed to be the 60 carats Nur-ul-Ain diamond, presently studded in a tiara also in Iranian Imperial collection.

The Cora Sun-Drop was mined in Africa and polished by Cora International, a company that specializes in very large and fancy color diamonds.

The diamond is on display until August this year.

The Ekati Spirit Diamond

The Ekati Spirit Rough Diamond From Canada's Northwest Territories

A 78-carat rough diamond from the Ekati mine in Canada’s Northwest Territories was sold in Antwerp this week at BHP Billiton’s diamond center for more than $6 million, which is a record for Canadian stones. The previous record was for a 10.22 carat gem, also from Ekati, which sold for $1.2 million. The stone was named the Ekati Spirit by an employee after a company contest.

The stone is internally flawless and is considered to be the mine’s most significant gem-quality finding in the last 13 years. It’s not the biggest stone to come out of the mine, that would be a 182ct stone found two years ago, but that stone was of poorer quality.

No word yet on who the buyer is, although it’s hard not to see a big stone and wonder if Laurence Graff or maybe Lev Leviev is behind the transaction. It’s also not clear if the stone will be cut and set. Stones lose a significant amount of weight when cut so it will be interesting to see what this stone looks like after the master cutters get their hands on it. With stones of this size and value, the diamond plotters often strategize for months, using computer modeling and other methods, before making that first fatal cut.

Accompanied by four reports dated from 6 March 2007 to 3 June 2008 from the Gemological Institute of America with the following details:

Report Date Weight Colour Clarity
10454112   03/06/08   10.12 D VS2
16948833   07/04/08   9.64 E VS1

Also accompanied by two supplemental letters by the Gemological Institute of America stating the 2.48 and 2.03 carat diamonds have been determined to be a type IIb. Type IIb diamonds are very rare in nature (from the laboratory’s experience, less than one half of one percent) and contain small amounts of boron that can give rise to a blue or gray coloration. An unusual property of type IIb diamonds is that they are semi-conductors and conduct electricity. Historically, the ancient mines of India produced occasional blue diamonds but today the most significant source is limited to the Cullinan (formerly Premier) Mine in South Africa.

Among famous gem diamonds, the 70.21 carat Idol’s Eye and the 45.52 carat Hope are examples of type IIb.

The Tiffany Yellow Diamond

16

The Tiffany Yellow Diamond

The Tiffany Yellow Diamond is one of the largest yellow diamonds ever discovered  It weighed 287.42 carats  in the rough when discovered in 1878 in the Kimberley mine in South Africa and was cut into a cushion shape of 128.54 carats with 90 facets—32 more than a traditional round brilliant—to maximize its brilliance.

Discovered in South Africa 1877, the stone was purchased by New York jeweler Charles Tiffany.  His gemologist, George Frederick Kunz, studied the gem for a year before beginning to cut it; reducing it from 287 carats (57.5g) to its current size. The cutting was carried out in Paris.  Kunz was a mere 23 years old at the time.

The diamond is known to have been worn by only two women during its lifetime. It was worn by Mrs. Sheldon Whitehouse at the 1957 Tiffany Ball held in Newport, Rhode Island, mounted for the occasion in a necklace of white diamonds. It was subsequently worn by Audrey Hepburn in 1961 publicity photographs for “Breakfast at Tiffany’s”.

Audrey Hepburn In "Breakfast At Tiffany's"

A publicity photo of Audrey Hepburn in the 1961 filmBreakfast At Tiffany’s” did a lot for the Tiffany image.  Tiffany’s Stores and the film are now forever associated with each other. The photo above shows the stone set in the “Bird on the Rock” brooch, which was designed by the famous Tiffany jeweler Jean Schlumberger. The piece is the Tiffany Yellow’s most well-known setting, and is the setting it remains in to this day.
