Flexible Investment Options

The Gemological Institute of America (GIA) developed the 4 Cs – Color, Clarity, Cut and Carat Weight. They used this as a benchmark to how a diamond is valued. Previous to this internationally recognized grading system, there were no such standards in place. Hence a value of a diamond was very subjective.

  • Color

    The GIA developed the D-to-Z color grading scale 50 years ago to show the range of color that a diamond has. ``D`` represents the colorless spectrum; while the opposite side of the spectrum is ``Z`` which represents the light color end.

  • Cut

    Natural Fancy Colored Diamonds are unique with graining to show its colors. If your intent is to turn your loose diamond investment into jewelry, then the right type of cut (size and shape) will make all the difference in the value of your Fancy Colored Diamond.

  • Clarity

    Fancy Color Diamonds will naturally have graining to them. They generally will not be as clear as a color-less diamond. However, a low clarity FCD can still be highly sought after. As long as these FCDs have an exquisite face-up color, they will be in high demand!

  • Carat

    The carat is the weight of the diamond. The bigger the diamond the rarer it is. However, when it comes to investing in loose natural colored diamonds, it’s better to diversify your portfolio. Hold more variety to ensure that you maximize your short and medium term returns.

3 Decades of growth

Not only do they make wonderful additions to any jewelry collection, colored diamonds also prove to be an amazing investment opportunity as their demand and value have shown significant growth in the past 3 decades.

The 1990's

It is safe to assume that the 90’s brought the first ground breaking record for the color category with the Graff Pink Supreme diamond. This 10.83 carat, pear cut, Internally Flawless, Fancy Vivid Purplish-Pink stone was sold in Christie's 1993 Geneva auction for more than $6.4 million. This translates to approximately $591,000 per carat; a remarkable price for a colored diamond in the early 90’s.

The 2000's

Three of the most coveted pink diamonds to ever be sold came to auction within just one year of each other, garnering huge attention and even bigger sales prices.

The first was the Vivid Pink diamond. This 5 carat, cushion cut, VS1, Fancy Vivid Pink stone made a staggering appearance in Christie's 2009 Hong Kong auction where it sold for $10.78 million (yielding slightly more than $2 million per carat). The clarity and color classification of this diamond makes it one of the most expensive pink gems per carat to have ever sold at auction until that time.

It goes without saying that the Graff Pink amazed the world when it was able to surpass the previous price record only a year later. This 24.78 carat, emerald cut, lla, Fancy Intense Pink managed to fetch $46 million (approximately $1.86 million per carat) at Sotheby’s 2010 Geneva auction. This did not only make it the most expensive pink gem up to date, but also the most expensive diamond ever purchased at a public auction. Since then, the gem has gone under ever more processing and currently weighs 23.88 carats and has been upgraded to an Internally Flawless Fancy Vivid Pink stone, further increasing its overall value.

The Graff Pink

The Perfect Pink was another stone that manage to fetch an astounding price of $23.3 million (or approximately $1.64 per carat) at Christie's 2010 Hong Kong auction. While the 14.23 carat, rectangular cut, lla, Fancy Intense Pink was not able to break any records for its category, it was the most expensive pink diamond sold by Christie's to that date. What’s more remarkable is that all three of these diamonds were sold for these astronomical price tags during the height of the financial crisis.

The Last Ten Years

The last five years continued to feature diamonds fetching jaw dropping prices, constantly setting new records for the category.

The ``Sweet Josephine`` is a remarkable stone purchased by billionaire businessman Joseph Lau during Sotheby’s 2015 Hong Kong auction. The 16.08 carat, cushion cut, Fancy Vivid Pink sold for $28.7 million (approximately $1.78 million per carat). Despite not breaking a price/carat ratio record, the Sweet Josephine’s price is still remarkable and the stone itself is worth mentioning on the list for its beauty.

Last year, the Unique Pink came close to setting a new price per carat record; however it fell short of the record set by the Vivid Pink back in 2009. The 15.38 carat, pear cut, Fancy Vivid Pink gem ultimately sold for $31.6 million at Sotheby's Geneva auction. Despite not setting any new price records, the Unique Pink holds the record for the largest diamond of such caliber in its category.

The Pink Star

The King of 2017 (and of All Time)

2017 was one of the most robust years in terms of record breaking pink diamonds. The Pink Star made a return and this time officially shattered the record for most expensive pink stone (and most expensive colored diamond) to ever be sold at a public auction. This truly magnificent gem managed to fetch $71.2 million on April 4 at Sotheby’s Hong Kong auction last year, and was bought by renowned jeweler Chow Tai Fook.

The Future of Pink Diamond Value

Pink diamonds have shown a continual growth in value year over year. At the upper echelon, these pink diamonds see an average price per carat of $1.5 to $3 million per carat. Investors and collectors are taking notice of these increasing values, and as supply decreases with the upcoming closure of the Argyle Diamond Mine, the demand is sure to continue to drive up this price.
