(previous purchase ca 1950) The Year of the Pink Diamonds
2010 SOLD 45.4 MCHF including premium
For several years, the fancy vivid blue diamonds obtained top prices. They are now in a close competition with pink diamonds, which have the advantage that top gemstones are bigger.
This trend accelerated on 1 December 2009, when a fancy vivid pink weighing 5 carats reached HK $ 83M including premium at Christie's in Hong Kong, i.e. U.S. $ 2.1 million per carat.
I have already discussed a few days ago the Perfect Pink, a fancy intense pink of VVS2 clarity weighing 14.23 carats, estimated HK $ 110M by Christie's, for sale on November 29.
In this fall, it has found a serious competitor. On November 16 in Geneva, Sotheby's auctions another fancy intense pink diamond, also of VVS2 clarity, also emerald cut, but bigger. Weighing 24.78 carats, it is mounted on a ring and estimated CHF 27M. It is illustrated in the article shared under Creative Commons protocol by LeBlogLuxe. This diamond was already known: 60 years ago, it was purchased to Harry Winston. It had never come back on the market.
Here are two recent examples that confirm the popularity of the pink color.
On October 3 in Toronto, Circa Auctions sold Can $ 2.3M a fancy intense orangy pink weighing 10.11 carats, clarity not found in the catalog.
On October 6 in Hong Kong, Sotheby's sold HK $ 60M including premium a diamond ring including a fancy vivid pink, VS2 clarity, weighing 6.43 carats.
POST SALE COMMENT
I had no doubt before the sale, and nobody can have a doubt now: the fancy intense pink diamond sold by Sotheby's is one of the most outstanding lots of current year. The result, CHF 45.4 million including premium corresponds to a value per carat never achieved previously at auction for a diamond of that size: 1.8 MCHF per carat.

(previous purchase 1960) The Mystery of the Little Prince
2013 SOLD 39.3 M$ including premium
On April 16 in New York, Christie's sells a cushion-cut pink diamond weighing 34.65 carats. It is identified as historic, which mostly means that some ancient information is available. Here is the link to the catalog.
This diamond has not been seen publicly since 1960. It was then bought £ 46K at auction by Van Cleef & Arpels, who named it the Princie Diamond by friendship with the young prince of Baroda.
I found on the web a page made before the recent resurgence of the Princie Diamond, in which it is fifth in a list of the most famous pink diamonds, but with a wrong color shade.
Its true color, fancy intense pink, is a pleasant surprise, because this is one of the best and rarest colors. The 24.78 carats Graff Pink, sold CHF 45.4 million including premium (U.S. $ 1.85 million per carat) by Sotheby's on November 16, 2010 is also a fancy intense pink.
The provenance of the Princie was not revealed in 1960. The press release from Christie's tells that the seller was the Nizam of Hyderabad himself, which supports the hypothesis that this diamond had been extracted from Golconda.
Unfortunately, its VS2 clarity is not excellent. The Graff Pink, VVS2, is better by two grades.
On 6 October 2010, Sotheby's sold HK $ 60M including premium a VS2 fancy vivid pink weighing 6.43 carats, which approximately corresponds to U.S. $ 1.15 million per carat.
POST SALE COMMENT
The market is sometimes of a surprising regularity. I gave here above an example at $ 1.15 million per carat for a diamond of same color and same clarity.
The Princie was sold $ 1.135 million per carat including premium. Its exceptional size has generated an extraordinary price: $ 39.3 million including premium.

A Blue Diamond for Oppenheimer
2016 SOLD for CHF 57M including premium
Throughout the twentieth century the De Beers cartel managed to control the diamond trade, accumulating an immeasurable wealth. The trust becomes a family business when a former buyer of diamonds of German origin named Ernest Oppenheimer becomes chairman of the company in 1929.
London is a hub for international operations and price controls. Sir Philip Oppenheimer retired in 1993 after 45 years as head of the Central Selling Organization of the cartel. This powerful position enabled him to keep exceptional gems.
On May 18 in Geneva, Christie's sells the Oppenheimer Blue that had belonged to Sir Philip. Weighing 14.62 carats, it is the largest fancy vivid blue diamond ever offered at auction. It is estimated CHF 38M, lot 242. It has been set on a ring by Verdura.
The clarity of the Oppenheimer Blue is excellent, graded VVS1 by the GIA. However, it does not reach the absolute purity of the Blue Moon, cushion cut to 12.03 carats, sold for CHF 49M including premium by Sotheby's on November 11, 2015, whose stunning clarity generates a phosphorescence effect under ultraviolet radiation.
The exceptional saturation characterizing the fancy vivid blue hue is enhanced on the Oppenheimer Blue by a highly efficient rectangular cut.
I invite you to admire this masterpiece of jewelry in the video shared by Christie's :

1999 A Fistful of Blue Diamonds
2016 SOLD for HK$ 250M including premium
De Beers exhibited their finest diamonds at the Millennium Dome in London throughout the year 2000. The Millennium Star is an astonishing white diamond weighing 203.04 carats. Facing it in the cabinet, eleven blue diamonds are totaling 118 carats. All these wonders had been extracted from the Cullinan mine.
One of these blue diamonds was oval cut. Weighing 10.10 carats, it is not the largest of the eleven but it is indeed the most spectacular. It was certified Fancy Vivid Blue Flawless in 1999 by GIA with the designation De Beers Millennium Jewel 4. Mounted on a ring in a surrounding of small white diamonds, it is estimated HK $ 235M for sale by Sotheby's in Hong Kong on April 5, lot 1843.
This unprecedented treasure insured altogether for £ 350M excited high appetites during the show at the Dome. On November 7, 2000, a commando of four equipped with a ten ton earth digger, sledgehammers, smoke bombs, gas masks and bulletproof vests come into the Dome, ready to celebrate the new millennium with the biggest heist ever.
The gang was under surveillance and 200 police officers had been mobilized. The head of the counter operation had decided to let the robbers go up to the showcase window for security reasons because arrests are easier in a closed room.
I invite you to watch the short video shared by Sotheby's to announce the sale of Jewel 4.

2003 The Pink Star
2013 recorded 76 MCHF including premium, UNPAID
2017 SOLD for HK$ 550M including premium
The Pink Star is unquestionably and by far the greatest polished diamond that ever hit the auction market. It should have fetched CHF 76M including premium at Sotheby's on November 13, 2013 but the buyer was unable to pay and its sale was cancelled.
Its come back was eagerly awaited by all the fans of highest jewelry and of auction history. It will be sold by Sotheby's in Hong Kong on April 4, lot 1801. It is estimated in excess of HK$ 468M currently worth US$ 60M, according to the press release of March 20.
The essay below is based on my 2013 discussion :
Its subtle color, Fancy Vivid Pink, is the best graded among diamond colors. Internally Flawless means a perfect clarity. Its weight, 59.60 carats, is the highest recorded for finished flawless diamonds of that color. Its oval shape and its polish are the perfect result of two years of work executed by Steinmetz Diamonds.
It comes from a rough gem of 142.5 carats unearthed in 1999 by De Beers somewhere in Africa, which is currently the best location for new fabulous diamonds. Its mixed cut had required more than 50 subsequent models from epoxy casts. It was unveiled to the public in 2003.
It exceeds in all its features the Graff Pink, sold for CHF 45.4 million including premium by Sotheby's on 16 November 2010, which had 24.78 carats, a VVS2 clarity and a fancy intense pink color slightly lower in theory than the fancy vivid but indeed highly striking in this specimen.
The Pink Star is expected beyond US $ 60M, a suitable and even conservative estimate when we consider that it is "only" US$ 1M per carat, but nevertheless ambitious because no other gem has ever reached such a price at auction. (Note that this expected value has been kept unchanged before the 2017 sale).

2014 In a Blue Moon
2015 SOLD for CHF 49M including premium
The ground continues to unearth important diamonds. Yet, the discovery announced by Petra Diamonds in January 2014 of a 29.62 carat blue gem from the much famous Cullinan mine in South Africa aroused a particular interest in the diamond community.
The new diamond is fancy vivid blue without inclusion, which is already a great rarity. It was purchased by Cora International, headquartered in New York, which processed it. This fancy vivid blue cut to 12.03 carats is the largest internally flawless blue diamond in cushion shape.
Once completed, it revealed even more exceptional qualities. Its ocean blue color is perfect without a secondary hue. It has no fluorescence. An exposure to ultraviolet radiation generates an intense orange-red phosphorescence that persists for about twenty seconds, a sensational feature which is known only to a few blue diamonds of absolute purity.
It is a masterpiece in both its size and features. It was named The Blue Moon in reference both to its shape and to the saying 'Once in a blue moon' that means a total rarity. It seems inconceivable to find better in its class, especially since the production of the Cullinan mine tends to decrease.
The Blue Moon is estimated between $ 35M (CHF 34,2M) and $ 55M (CHF 53,7M), for sale by Sotheby's in Geneva on November 11, lot 513. I invite you to watch the video shared by Sotheby's.

2016 Three Continents for a Stone
2017 SOLD for CHF 33.5M including premium
On November 14 in Geneva, Christie's sells as lot 505 a diamond type IIa, D color, Flawless clarity. Weighing 163.41 carats, it is the largest perfect white diamond ever offered at auction and one of the largest ever inspected by the GIA. This performance is not the result of chance but of the involvement of the best specialists in the world.
The steps are told in detail by Christie's in the featured post.
The rough stone is extracted in Angola in February 2016. Weighing 404 carats, it is promising while being far from the records. Its quality is confirmed in New York by spectrography. For several weeks a team of experts researches the defects of the crystal.
Its bean form is not directly usable. In June, the world's best diamond cleaver with more than 50 years of experience cuts the stone in two halves from the middle. The polishing in emerald cut lasts six months, facet after facet.
They must now design a piece of jewelry highlighting this unprecedented wonder. The diamond is brought in December 2016 to De Grisogono in Geneva, which designs an asymmetrical necklace of emeralds and diamonds in 44 cm length. The jewel entrusted to Christie's then travels around the world before returning to Geneva for its auction sale

Blue for Boys and Pink for Girls
2017 SOLD for CHF 42M including premium
On May 16 in Geneva, Sotheby's sells an exceptional blue diamond, lot 377 estimated CHF 38M. It is in the best color, Fancy vivid blue, and perfect clarity, Internally Flawless (IF). The concentration of boron atoms in its crystal made it classify as Type IIb by the GIA, rarer than the Type IIa.
It weighs 14.54 carats, compared with the 14.62 carat of the Oppenheimer Blue which was sold for CHF 57M including premium by Christie's on May 18, 2016.
The Blue Moon that became after its sale the Blue Moon of Josephine is also a Type IIb. Sold for CHF 49M including premium by Sotheby's on November 11, 2015, this diamond weighing 12.03 carats owes its culminating value at US $ 4M per carat to an absolute purity generating a sensational effect of phosphorescence after exposure to ultraviolet rays.
The diamond that comes in the next sale is pear shaped. Someone had the idea to choose a pink diamond of comparable cut and size. The two gems hanging each to a suite of two white diamonds thus constitutes temporarily the most sumptuous pair of earrings of all time. They are named Apollo and Artemis by reference to the beautiful twins of Greek mythology.
Nevertheless this pair will be divided. Artemis is estimated CHF 12.5M, lot 378. It is a Fancy intense pink Type IIa and VVS2 clarity weighing 16.00 carats. The market generally prefers a Fancy vivid pink. Of the same Type, clarity and form, a Fancy vivid pink weighing 15.38 carats was sold for CHF 31M including premium by Sotheby's on May 17, 2016.

The Orange
2013 SOLD 32.6 MCHF including premium
It is rare to have a wonder of nature, in a beautiful color, more than two times heavier than the largest other known diamond of same color and clarity : on November 12 in Geneva, Christie's sells a Fancy Vivid Orange diamond weighing 14.82 carats, VS1 clarity, pear shaped.
A wide range of colors of diamonds is possible in nature between yellow and pure orange. However pure orange is extremely rare, and it is certainly more striking than other mythical colors such as dark red. An old classification designated the Fancy Vivid Orange as the fire diamond.
All great diamonds have a name. It was not difficult to create it for this one. It has no competitors in its class. It is The Orange, simply. Here is the link to the catalog.
This exceptional diamond is estimated CHF 16M before fees, corresponding to U.S. $ 1.15 million per carat. It is very difficult to actually predict its price. We may however compare it to a fancy vivid pink VS2 weighing 6.43 carats, of a prestigious but less rare color, that was sold for U.S. $ 1.15 million per carat including premium by Sotheby's on October 6, 2010 in Hong Kong.
POST SALE COMMENT
The estimate was too conservative. This stunning diamond was sold for CHF 32.6 million including premium (US $ 2.4 million per carat).

Unique Qualities of a Pink Diamond
2016 SOLD for CHF 31M including premium
For physicochemical reasons, pink diamonds are different from other colored diamonds. They have in common with colorless diamonds the lack of chemical impurities. Their color is due to the distortion of the crystal.
For this reason, pink diamonds offer a continuous range of hues from the paler (faint) to the most saturated (fancy vivid). The fancy intense pink often discussed in this column is less prestigious than the fancy vivid. The atomic intrusions can also generate more complex pinks approaching to purple or orange.
The most exceptional diamond ever offered at auction was the Pink Star, fancy vivid pink internally flawless weighing 59.60 carats. Its sale by Sotheby's on November 13, 2013 for CHF 76M including premium was later canceled after buyer payment deficiency.
On May 17 in Geneva, Sotheby's sells the Unique Pink, lot 495estimated CHF 26,9M.
This fancy vivid pink of astonishing transparency and splendid purity offers a very saturated color. The total absence of atomic intrusions in the carbon crystal was verified by spectroscopy. Without approaching the weight of the Pink Star, the Unique Pink remains nevertheless very large in its category, 15.38 carats. It is VVS2, the best clarity below internally flawless and VVS1.
Because of their creation by pressure during the formation of the rock, the pink gems have an axis. The jeweler takes it into account to choose the shape. The Pink Star, absolute wonder of mineralogy, has been cut as a perfect oval obtained after two years of work by Steinmetz Diamonds. The Unique Pink was pear shaped by Cora International.
