1604-(1610) The Coronation of Marie de Médicis
2012 SOLD 9 MCHF including premium
Nicolas de Harlay, sieur de Sancy, owned two remarkable diamonds. He used them to fuel the greed of kings and queens.
His pale yellow diamond of 55 carats took his name: the Sancy. In 1604 it was bought by James I of England. It joined the Régent in the Louvre.
Henri IV and Marie are a dissimilar couple. The Bearnese peasant seeks to counteract the trends to luxury of his Florentine wife. Perhaps to comfort her after missing the Sancy, Henri buys for Marie the other prestigious gem, also in 1604. This 35-carat white diamond of pear double rose cut was later called the Beau Sancy.
Marie, married in 1600 long after the beginning of Henri's reign, had not yet been crowned, to her dismay. The king finally gave away, again. During the coronation ceremony, on May 13, 1610, the Beau Sancy adorns the crown of the queen. The next day, Henri IV is assassinated.
The Beau Sancy has always remained in royal European families. It is estimated CHF 2M, for sale by Sotheby's in Geneva on May 15.
It is illustrated in the article shared by La Tribune de Genève. Its ancient cut with bulky shapes is outdated, just like the complicated cut of the yellow Sancy based on a shield shape.
POST SALE COMMENT
The Beau Sancy was sold CHF 9M including premium, well above its estimate. Its price per carat, CHF 250K, is remarkable.
Such enthusiasm for a historical gem is not common. Hopefully its success will attract to the market other exceptional historical pieces.

The Archduke Joseph
2012 SOLD 20.4 MCHF including premium
A star from the history of auctions is coming back.
In Geneva in November 1993, Christie's sold CHF 9.7 million the Archduke Joseph diamond. It was a fabulous price for the time even after considering that the Swiss currency was at one third below the U.S. dollar.
This is one of the largest perfect diamonds of Golconda type : D color and internally flawless. Being now at 76.02 carats, it achieves a weight equal to 72% of the Koh-i-Noor, a remarkable performance that makes it one of the most desirable gems available on the market.
Its antique cut is cushion-like, although for such big diamonds it is not quite possible to fully meet a standardized shape classification. Like many old diamonds, it has been reworked in the last century to improve its clarity and symmetry.
Previously owned by the Habsburgs, it bears the name of a prince who was briefly regent of Hungary at the time of the fall of his dynasty.
It is now presented by Christie's in Geneva on November 13.
Considering that bigger diamonds appeal to a higher price per carat, Christie's has calculated for this perfect diamond an estimate range of U.S. $ 15M to 25M. The upper estimate is an attempt to exceed the record for the highest price per carat registered at auction for a colorless diamond.
It is illustrated in the article shared by Professional Jeweller.
POST SALE COMMENT
The result meets the expectations of Christie's: Archduke Joseph was sold CHF 20.4 million including premium.
For a comparable quality, when the diamond is bigger, the price per carat is higher. This one went to US $ 280K, the highest recorded price per carat at auction for a colourless diamond.
It is indeed a great result for that diamond which I described as nearly comparable to the Koh-i-Noor.

The Taylor
2011 SOLD 8.8 M$ including premium
Two diamonds were named from Elizabeth Taylor.
The best known was the Taylor Burton Diamond, weighing 69 carats, purchased by Richard Burton in 1969. It was the first diamond over one million dollars. Liz sold it for the benefit of a charity at the time of her divorce from Richard.
The other, which is the subject of this article, was called the Krupp Diamond before being bought at auction by Richard Burton in 1968. It became the favorite diamond of Liz Taylor, which is a great compliment since the actress was an expert in that field and loved to wear her jewelry. Its name was changed to Elizabeth Taylor Diamond.
Technically, it is a diamond of D color, type IIa, clarity VS1 that can be reworked to potentially internally flawless. Its unusual shape is close to the Asscher cut, a variant of the emerald cut with more balanced proportions. It is mounted on a platinum ring.
It only weighs 33.19 carats, but when it shines in all its glory it is one of the finest diamonds in the world.
Estimated $ 2.5 million, it is the star lot of the Taylor collection, for sale by Christie's in New York on December 13. Here is the link to the catalog.
POST SALE COMMENT
The Elizabeth Taylor Diamond can now claim to be the most beautiful white diamond in the world. It was sold for $ 8.8 million including premium.
Its price per carat is $ 265K. By comparison, the Annenberg Diamond, 32 carats in Asscher cut, was sold for $ 240K per carat by Christie's on October 21, 2009.

2011 - 118 Carats Flawless
2013 SOLD 240 MHK$ including premium
Southern Africa has replaced Golconda as the source for the best diamonds in the world, type IIa. The arrival on the market of exceptional pieces of very recent extraction certainly demonstrates improvements in the techniques of prospecting, but also in the preparation of perfect diamonds.
On May 15, 2013, Christie's sold for CHF 26M including premium a white diamond, D color and Flawless. Pear shaped and weighing 101.73 carats, it came from a rough stone of 236 carats of the Jwaneng mine in Botswana. It was named The Winston Legacy after the sale.
The diamond for sale by Sotheby's in Hong Kong on October 7 is also D and Flawless, but bigger: 118.28 carats. Here is the link to the catalog.
It is oval cut from a 299 carat rough stone discovered in 2011 in a deep mine of southern Africa whose detailed location is not revealed. Its polishing and symmetry are considered excellent by the gemological laboratories.
The press release announces a lower estimate of HK$ 220M.

2010s The Great Star of Botswana
2013 SOLD 26 MCHF including premium
Since the depletion of Golconda, the best pure diamonds of IIa type are extracted in Austral Africa: South Africa, Lesotho, Botswana.
Botswana's mines are operated jointly by the government and by De Beers, with all the precautions that you can imagine. Indeed the small town of Jwaneng was founded in 1982 as a closed community only accessible by permission of the government.
Because of this relatively recent operation, fabulous gems are still waiting to be discovered. The modern art of diamond will do the rest, as technological advances now enable to cut diamonds of perfect shape and symmetry.
Consider an example from the past. The Cullinan, extracted in Transvaal in 1905, was a gem of 3106 carats. Nine major diamonds were cut from it, including the Great Star of Africa achieved at 530.2 carats after eight months of preparation.
On May 15 in Geneva, Christie's sells a perfect diamond (type IIa, D color, flawless). It is pear shaped at 101.73 carats representing an outstanding yield for that rough stone of 236 carats extracted in Jwaneng. Its polishing required 21 months of work.
The price per carat increases for bigger diamonds. Thus, the Archduke Joseph, sold by Christie's in Geneva on November 13, 2012, was recorded at $ 280K per carat (total price CHF 20.3 million including premium for 76.02 carats).
The new wonder from Jwaneng is the biggest perfect diamond ever presented at auction. Although having no other history than its discovery and preparation, it may certainly exceed the Archduke Joseph.
POST SALE COMMENT
This exceptional diamond has been sold CHF 26M including premium. The price per carat, U.S. $ 270K, is consistent with the price obtained on the Archduke Joseph.

The Pure Heart of Christie's
2011 SOLD 9.6 MCHF including premium
On the occasion of Valentine's day, Christie's announced a great heart shaped diamond. Its characteristics deserve to be listed in detail.
It is in D color: exceptional white of the upper category. We can not imagine better.
It weighs 56.15 carats.
Just remember another D, the Annenberg diamond, sold $ 7.7 million including premium by Christie's on October 21, 2009. Emerald cut, it only weighed 32 carats. The price per carat, $ 240K, was sensational.
Coming back to our heart. It is pure, of class IF (Internally Flawless), meaning that no inclusion is visible at x 10 magnification. It is remarkable for a diamond of this size. We can not have better.
It is also of type IIa, meaning a slow geological formation that excluded nitrogen. This feature, which affects less than 1% of diamonds, is the cause for its exceptional transparency. If in addition there had been traces of boron, it would be blue or gray.
Among the ten most common diamond shapes, the heart is the only one that provides a concave surface. It is a technical feat.
Unmounted in a jewel, this marvel is estimated CHF 9M, for sale in Geneva on May 18, corresponding to $ 160K per carat.

The Perfect Emerald Cut White Diamond
2015 SOLD for $ 22M including premium
The southern African ground is full of wonderful stones. The perfect white diamond for sale by Sotheby's in New York on April 21 is another example of a recent extraction. It weighs 100.20 carats after being worked from a rough gem of 200 carats, which is an excellent weight ratio facilitated by modern technology.
From the mineralogical point of view, it is perfect : Type IIa, D color and internally flawless despite its large size.
Compared to other diamonds of same quality and comparable weight, it has the unique feature of being emerald cut, offering one of the best possible shine. It is estimated $ 19M, lot 357, and was the subject of a detailed press release.

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

2016 A New Signature in Paris
2016 SOLD for CHF 17.6M including premium
Paris remains a capital of luxury. A new workshop has been created with a single specialty : assembling jewels composed of diamonds that are perfect by their white D-Type color, their flawless clarity and their symmetry.
Diamonds are forever and elegance too. These newcomers connect with the past by taking the name Boehmer et Bassenge.
This double name that had gone into the oblivion of history was that of the jewelers entrusted by Louis XV in 1772 to create the most stunning necklace of all time for a presentation to his mistress Madame du Barry. The necklace totaling 2,840 carats of diamonds was assembled but not delivered because of the king's death. It was dismantled in 1785 in the most sensational scam case of the Ancien Régime : l'Affaire du collier de la Reine.
The new Boehmer et Bassenge company targets an extreme quality and their outputs will be of an utmost rarity. They chose Christie's for selling two of their earliest masterpieces. The auction takes place in Geneva on November 15 without a reserve price on these lots.
Miroir de l'Amour is a pair of earrings 7 cm long, lot 188 estimated CHF 20M. Each element consists of a pear-shaped diamond of over 50 carats, namely 52.55 and 50.47 carats, topped with a rich cluster of smaller diamonds.
Le Jardin d'Isabelle is a necklace, lot 187 estimated CHF 8M. This jewel consists of two lines centered on diamonds respectively weighing 31.38 carats and 12.11 carats.

2017 SOLD for CHF 14.8M including premium
The heart shape is a romantic symbol. For a diamond it is a technical feat. The heart is a modified brilliant. It is the only configuration of a diamond carved to include concave surfaces.
The difficulty consists in achieving a geometric balance without disparity between the two halves of the heart while maintaining a perfect sharpness in the cleft. Any mistake appears ridiculous to a demanding user.
