The Most Expensive Pink Diamonds – Top 10

Pink Diamonds are one of the rarest types of Diamonds, with only 0.01% of mined Diamonds estimated to be gem-quality pink and this rarity, combined with the beautiful color and look of the stones means that they are also quite expensive.

But even amongst the rare and valuable there are exceptions and in this post, I will be listing the 10 most expensive Pink Diamonds ever to be sold at public auction and there are some stunners!

10: Sweet Josephine

Sweet Josephine Pink Diamond

Weight: 16.08 Carats
Sale: Christie’s, Geneva, 10th November 2015
Sale Price USD: $28.5 Million

The Sweet Josephine Diamond holds the distinction of being the largest cushion-shaped, fancy vivid pink diamond ever to be offered at auction.

The GIA also graded Sweet Josephine as having VVS2 clarity.

The platinum and gold mount, with twin halos of smaller diamonds in which Sweet Josephine is set, only adds to the appeal of this amazing Pink Diamond.

9: The Sakura Pink Diamond

The Sakura Pink Diamond

Weight: 15.81 Carats
Sale: Christie’s, Hong Kong, 23rd May 2021
Sale Price USD: $29.2 Million

Not only is The Sakura a great name but the stone itself is also incredible and was the largest Flawless or Internally Flawless, Fancy Vivid Purple-Pink, Natural Color diamond GIA has graded as of February 27, 2020.

With the amount of diamonds GIA have graded, that is impressive.

What is also quite exceptional around the sale price is that The Sakura Pink Diamond sold when the world was in the middle of a global pandemic and it would be interesting to know if it would have achieved a higher price if sold in more normal times?

8: The Unique Pink

The Unique Pink Diamond

Weight: 15.38 Carats
Sale: Sotheby’s, Geneva, 17th May 2016
Sale Price USD: $31.5 Million

To be called The Unique Pink means that this Pink Diamond must be well… unique and I hope it would be for $31.5 million!

The GIA, who graded this stunning Pink Diamond also included a very superlative monograph along with the report and this paragraph describes it in a way that is better than I ever could:

“In addition to Fancy Vivid colour and a remarkable weight of 15.38 carats, the Unique Pink was reported to display stunning clarity and exceedingly pure (type IIa) structure. This rare combination of superior qualities allows the Unique Pink to hold the distinction of a truly exceptional gem”

7: The Pink Promise Diamond

The Pink Promise Diamond

Weight: 14.93 Carats
Sale: Christie’s, Hong Kong, 28th November 2017
Sale Price USD: $32.4 Million

The Pink Promise is one of the smaller stones on the list, even though 14.93 carats is still impressive for a Pink Diamond but the fact that it sold for $32.4 million goes to show how impressive this stone is.

I also personally like the platinum and diamond mount, which enhances the center stone.

The accompanying GIA reports also states that “the diamond is fancy vivid pink colour, VVS1 clarity; and a Diamond Type Classification letter stating that the diamond has been determined to be Type IIa”.

6: The Eternal Pink Diamond

The Eternal Pink Diamond

Weight: 10.57 Carats
Sale: Sotheby’s, New York, 8th June 2023
Sale Price USD: $34.8 Million

The Eternal Pink Diamond was part of a record-breaking sale at Sotheby’s as it was one of two stones, alongside the Estrela de FURA to sell for more than $30 million in the same sale.

And it is easy to see why it achieved such as high price as it has a stunning Fancy-vivid Purplish Pink colour combined with Internally Flawless clarity and weighing over 10 carats makes this a very special Pink Diamond.

The diamond was graded by the GIA and the report included a monograph that described the stone as “a stunning specimen; one of nature’s great wonders transformed through artistry and ingenuity.” and it is very hard to disagree.

5: The Princie Diamond

The Princie Diamond

Weight: 34.65 Carats
Sale: Christie’s, New York, 16th April 2013
Sale Price USD: $39.3 Million

The Princie Diamond is one of the largest Fancy Intense Pink Diamonds to ever be offered at auction and while the color of the stone might not be as strong as some on the list, it is the size of the diamond that helped it achieve a $39.3 million price tag.

It is also the most expensive loose Pink Diamond to ever be sold at auction.

4: The Graff Pink Diamond

The Graff Pink Diamond

Weight: 24.78 Carats
Sale: Sotheby’s, Geneva, 16th November 2010
Sale Price USD: $46.1 Million

The Graff Pink as it was renamed held the record for the world’s most expensive Pink Diamond for over 6 years following its $46.1 million sale price in 2010.

Similar to The Princie Diamond, the Graff Pink is a Fancy Intense Pink Diamond with VVS2 clarity, which means it has a softer pink color than the fancy vivid pink diamonds.

But it is still an incredibly beautiful Diamond and the GIA did also say that stone could potentially be flawless after repolishing but this would mean that some weight would be lost.

3: The Pink Legacy Diamond

The Pink Legacy Diamond

Weight: 18.96 Carats
Sale: Christie’s, Geneva, 13th October 2018
Sale Price USD: $50 Million

The Pink Legacy Diamond was bought for $50 million in 2018 by Harry Winston, who know a thing or two about Diamonds!

And the 18.96 carat, Fancy Vivid Pink color combined with VS2 clarity and a somewhat unique cut makes this Diamond an absolute stunner.

While it came up a bit short in terms of sale price when compared to the world’s most expensive Diamond, It did achieve a world record price per carat for a Pink Diamond at just over $2.6 million per carat and would hold that record for a few years.

2: The Williamson Pink Star

The Williamson Pink Star

Weight: 11.15 Carats
Sale: Sotheby’s, Hong Kong, 7th October 2022
Sale Price USD: $57.7 Million

The most recent entry on the list is The Williamson Pink Star diamond, which didn’t break the record for the most expensive diamond but smashed the record of the price per carat.

This is because the 11.15 carat, Fancy Vivid Pink, Internally Flawless diamond achieved a price per carat of just over $5.1 million!

Which easily beat the previous record of $4 million per carat achieved by the Blue Moon of Josephine, when it sold in November 2015.

The stunning diamond was accompanied by a report from the GIA, which had an additional monograph stating ‘…The Williamson Pink Star diamond, is among the rarest of all gemstones…It is extremely rare to encounter large pink diamonds with an unmodified color in any shape, particularly with saturation. In addition to its exceptional color, the clarity is Internally Flawless – a special combination. Examples such as this are some of the rarest gems ever discovered.’

1: The Pink Star Diamond

The Pink Star Diamond

Weight: 59.60 Carats
Sale: Sotheby’s, Hong Kong, 4th April 2017
Sale Price USD: $71.1 Million

The Pink Star is one of the most historically significant diamonds ever to be sold at public auction as it holds a couple of distinctions:

  1. The largest natural, Fancy Vivid Pink Colour and Internally Flawless ever sold
  2. The most expensive Pink Diamond ever sold by some margin

And to clearly stand out on a list of incredible Diamonds is some achievement, it is also the world’s most expensive Diamond by over $10 million and understandably caused a stir in the jewelry world.

The GIA also stated that the Pink Star ‘is the largest Flawless or Internally Flawless, Fancy Vivid Pink, Natural Colour, diamond they have ever graded’.

The history of the stone is also fascinating as it took over two years to cut the Pink Star from the original 132.50 carat rough and was original unveiled in May 2003 at an event that coincided with the Monaco Grand Prix at which time it was known as the ‘Steinmetz Pink’.

Conclusion

There are some mind-blowing Diamonds and prices in this list and the combined sale price of all these Pink Diamonds is over $412 million!

That is an insane amount of money but as with all the expensive stones, it will be interesting to see what comes to market in the next few years and if any of them will crack the top 10.
