10 history-making pink diamonds offered at Christie’s
As Christie’s offers the largest fancy vivid purple-pink diamond ever to come to auction, jewellery specialist Marie-Cécile Cisamolo puts it in the context of other fabulous pink stones that have bedazzled our salerooms
Prices for top-quality, large pink diamonds have increased exponentially in recent years, driven by collector demand and increasingly limited supply. Pink diamonds gain their highly desirable colour as a result of a rare, naturally occurring slippage of the crystal lattice in the stone while it is forming deep within the Earth’s crust. Here we look back at some of the biggest and the best stones and pink diamond rings offered at Christie’s in recent times.
As the annual cherry blossom season reaches its peak, Christie’s is set to make history by offering the largest fancy vivid purple-pink diamond ever to appear at auction. The outstanding highlight in Hong Kong’s Magnificent Jewels sale on 23 May, ‘The Sakura Diamond' weighs 15.81 carats — almost one carat more than the previous record-holder — and carries an estimate of HK$195-300 million.
The size is significant because, in the increasingly rarefied world of pink diamonds, large rough stones are almost impossible to find and exceedingly difficult to cut. The stone is also prized for its clarity: while the majority of pink diamonds are graded SI (slightly included), and can look hazy even when less included, 'The Sakura Diamond' is graded Internally Flawless. The pink-purple colour is well-balanced and strongly saturated — an exceptionally sweet hue that matches the colour of cherry blossom. In other words, it’s not only a large and striking diamond, but an auspicious one, too.
Flanked on either side by shield-shaped diamonds, this pink
stone is set on a platinum and 18k rose-gold ring designed
by the British jeweller Graff. When it went under the hammer
in Hong Kong, ‘The Vivid Pink’ sold for more than double its low estimate
and achieved the highest price ever paid per carat for a
pink diamond at the time ($2,155,332). The record remained
unbeaten until the sale of ‘The Pink Promise’ by Christie’s
in 2017.
The Vivid Pink, an exquisite coloured diamond and diamond ring, by Graff. Sold for HK$83,540,000 on 1 December 2009 at Christie’s in Hong Kong
This example is certified ‘IIA’ by the Gemological Institute of America — meaning it
has a particularly rare, almost homogenous colour.
This square-shaped diamond, which is a particularly light shade
of pink, was given by Cardinal Mazarin to Louis XIV in 1661.
It then spent 225 years as part of the French crown jewels,
passing through the hands of four kings, four queens, two
emperors and two empresses, before its 1887 sale when the
royal treasury was dispersed and its whereabouts became unknown.
In 2017, while on a site visit to a client’s house, ‘Le Grand Mazarin’ was revealed from inside an old parcel paper to Christie’s jewellery
specialist Jean-Marc Lunel. ‘Holding such an important piece
of French royal history in my hands was unbelievable,’ he
would later recall of the historic diamond’s rediscovery.
Stored in a bank vault since the 1940s, this unique purplish-pink diamond is set in a Belle Epoque ring made by Dreicer & Co. and formerly belonged to the reclusive American mining and
railroad heiress, Huguette M. Clark. When it sold for almost
double its upper estimate in 2012, it became the most expensive pink diamond ever seen at auction in the United States.
The Clark Pink. A Fancy Vivid, cushion-cut purplish-pink diamond, 9.00 carats. Sold for $15,762,500 on 17 April 2012 at Christie’s in New York
The ring was the top lot of a collection of 17 of Clark’s jewels
that were auctioned by Christie’s, which also sold her collection
of paintings, by artists including Monet, Renoir and Whistler, two years later.

Harry ‘King of Diamonds’ Winston, this ring was nicknamed ‘The Martian Pink’ by his son Ronald, who was inspired by the
1976 launch of a US satellite to photograph the ‘red planet’
Mars, and the stone’s similar strong pink colour.
The Martian was certified as having virtually no nitrogen in
its crystalline structure and, unlike most pink diamonds,
which exhibit tones of purple, orange or grey, it shows absolutely
no trace of any secondary colour. As a result, it sold for
more than double its low estimate when it went under the
gavel in Hong Kong in 2012.
Only a few mines in the world produce pink diamonds, and of
those diamonds that are cut and polished only one in roughly
10 million will possess a colour pure enough to be graded Fancy Vivid.
A rare coloured diamond ring. Sold for CHF 18,127,500 on 15 November 2016 at Christie’s in Geneva
This large example, which is mounted between tapered baguette-cut diamond shoulders on a platinum ring, was certified Fancy
Vivid in June 2016 by the Gemological Institute of America,
helping it push past its top auction estimate and achieve
more than $18 million when it sold in Geneva in the same
year.
At the time of this stone’s sale in 2010, it was one of only 18 pink diamonds weighing more than 10 carats to have ever appeared at auction. And of those 18, none apart from this diamond had
ever been graded Fancy Intense Pink at the time of its
sale, which placed it in a league of its own.
Flanked on either side by two clear diamonds mounted in 18k
rose gold and white gold, the pink diamond sold for almost
30 per cent more than its upper estimate when it appeared in the Hong Kong saleroom, demonstrating a strong demand for
coloured diamonds in Asia.
Mounted in a diamond twin-surround and with a diamond-set hoop,
this ring set a new world-record price for any pink diamond
when it sold at Christie’s in Geneva in 2015. Owned by an
American family for 15 years prior to the sale, the stone
was at the time the largest cushion-shaped pink diamond
classified as Fancy Vivid Pink to ever come to auction.
After the sale the diamond, which sold for around $5.5 million
more than its lower estimate, was named ‘The Sweet Josephine’ by the winning bidder in honour of his seven-year-old daughter.
This pink stone, with its circular-cut
diamond surround featuring more pink diamonds and a platinum
ring, set a new price-per-carat world record for any pink diamond when it sold in 2017 — a whopping $2,175,519.
The diamond’s initial grading was Fancy Intense before the
jeweller, Stephen Silver, cut it down from 16.21 to 14.93 carats
in 2013, shaving off areas of inclusions after years of detailed
planning. The resulting stone was upgraded to the much rarer Fancy Vivid category, the highest possible colour mark
for pink diamonds.
This pink diamond was discovered about 300 years ago
in India, and was initially owned by the Nizams of Hyderabad.
It was first auctioned in 1960, where it was purchased for
£46,000 by Van Cleef & Arpels.
The diamond was promptly named ‘Princie’, and the house
threw a christening party for the stone in its Paris showroom.
The Princie Diamond. Sold for $39,323,750 on 16 April 2013 at Christie’s in New York
Of the seven million diamonds that have passed through the
Gemological Institute of America, no more than 40 have exhibited
a rare orange glow when examined under ultraviolet light,
and the Princie is the largest of all of them. This fluorescent
quality pinpoints the stone’s origin to the Golconda mines
of India.
As it is the largest Golconda-type Fancy Intense pink diamond
to ever be graded by the GIA, it’s little wonder that it sold
for almost $40 million when it appeared in the sale room in New York in 2013, making it the most expensive pink
diamond ever sold at Christie’s — a record it still holds.
