Pink Diamond Could Sell For $15 Million


The diamond world could be rocked with a new record later this year when this 8.41-carat purple-pink diamond goes up for auction at Sotheby’s Hong Kong Magnificent Jewels and Jadeite Autumn Sale.

The stone, originally mined by De Beers, weighed in at 19.54-carats in its rough form.   It will tour around the world with stops in Singapore, Taipei, New York, London, Geneva and Hong Kong leading up to the October 7th auction.

At the auction, the pear-shaped stone could sell between $12.8 million and $15.4 million (USD).   The per-carat selling record for a pink diamond was set in 2009 when a 5-carat stone sold for $2.1 million/carat.   If this purple-pink stone goes beyond estimate and sells for over $18 million, that record could be in jeopardy.

The largest overall sale for a pink diamond was for the Graff Pink Diamond, a 24.76-carat, Fancy Intense pink diamond that sold at auction in 2010 for $46.2 million or $1.86 million per carat.

In the years since those two massive pink diamond sales, the value of pink diamonds has continued to increased in value.   A situation that will only continue as the world’s main source of pink diamonds, the Argyle mine in Australia is expected to close by 2019.  

Top 10 Most Famous Heart Shaped Diamonds

1.   The Heart Of Eternity Diamond


Weighing in at 27.64 carats, this Fancy Vivid Blue diamond was recovered from the Premier Diamond Mine in South Africa.   The stone was first unveiled as part of the De Beers Millennium Jewels collection at at the Millennium Dome in London in 2000.

2.   The Blue Heart Diamond


Slightly bigger than the Heart of Eternity stone, this 30.82 carat diamond was found around 1909-1910.  The original owner was Cartier, however, it has been sold five times since and is currently on display at the Smithsonian Institute in Washington.

3.  The Gruosi Diamond


The largest black diamond in this shape, the Gruosi Diamond weighed in at 300.12 carats in the rough.   However, cutting the stone proved to be very fragile when being cut and in its current form weighs only 115.34 carats.   The stone is now the centrepiece of of a necklace featuring an additional 58.77 carats of smaller black diamonds, 378 white diamonds and 14.10 carats of tsavorite garnets, set in white gold.

4.   The Taj Mahal Diamond


The Taj Mahal Diamond was found in the 17th century and was inscribed in the Persian language using Arabic characters.   Translated, it says “Nur Jahan, Begum Padshah; 23; 1037″ – Nur Jahan, Lady of the Padshah; 23; 1037”.   This references Empress Nur Jahan, wife of Emperor Jahangir Shah as well as the Islamic calendar year 1037 which is actually 1628 according to our calendar.

The stone, set in a jade necklace and pendant, was made famous as a gift from Richard Burton to his wife Elizabeth Taylor on her 40th birthday.   It sold at auction after her death for $8.8 million.

5.   The Centenary Diamond


At 273.85 carats, it is the largest diamond on our list.  Recovered in 1986, it originally weighed 599 carats in the rough.   It took 5 years to get it to its current modified diamond cut shape.   It has never been sold at auction so no one is sure of its exact value.   However, it was ensured for over $100 million when it was unveiled in 1991.   To further add to its mystery, despite once being owned by De Beers, a current owner has yet to be confirmed.

6.  The Cullinan Diamond V


One of the nine diamonds cut from the original Cullinan Diamond, the largest gem quality diamond ever found.   Weighing in at 18.8 carats, it was given to Queen Mary by by the Government and People of South Africa in 1910.   Since then it has been most commonly used as part of a brooch with a platinum web with a scrolling millegrain and pavé-set border of brilliant diamonds.

After Queen Mary’s death in 1953, the brooch was passed on to her granddaughter, the current British monarch, Queen Elizabeth II.

7.  The Royal Purple Heart Diamond


At only 7.34 carats, the Royal Purple Heart Diamond is still the largest Fancy Vivid Purple diamond ever recovered.   It is believed to have been found in Russia but further details, including its current owner have never been confirmed.

8.  Christie’s 56-Carat Heart-Shaped Diamond


Part of Christie’s Magnificent Jewels Auction in May 2011, this 56-carat diamond was estimated to sell between $8 and $10 million but actually sold for $12 million.   It still holds the record for the most ever spent at auction for a heart shaped diamond.

9.  The Heart Of The Ocean Diamond


Yes, this is a fictional diamond from the 1997 film Titanic, but that doesn’t stop it from making our list.   In the film, the diamond was originally owned by Louie XVI and was cut into a heart shape just after the French Revolution.

The film itself went on to win the Best Picture Academy Award as well as 10 other Academy Awards.   It was the highest grossing film of all time until it was surpassed by the film Avatar 12 years later.

10.   The Argyle Amour Diamond


This very rare 2.61 carat pink diamond is the most valuable of this shape ever to come out of the Argyle Diamond mine in Australia.
