The Buyer’s Guide: Pink Diamonds

One of the most coveted of all natural fancy color diamonds is undeniably the pink diamond. Pink diamonds radiate romance and majesty, attracting collectors and investors from across the globe. Pink diamonds come in a magnificent ray of hues, ranging from pure petal pink and raspberry to peachy pinks. However, they can be quite challenging to find. It is this combination of rarity and exquisite beauty of colors that make the pink diamond an extremely rare and sought-after treasure.

Origin: Argyle Diamonds and Other Pink Diamond Sources

The Argyle Diamond Mine, situated in the Kimberly Region of Western Australia, produces 90 per cent of the world’s pink diamonds. While this appears as a vast output of pink diamonds, the mine’s production of these alluring stones account only for one tenth of one per cent of a full year’s production. These pink diamonds are highly prized, and owning such a diamond is a collector’s dream, “attracting on average 20 times the price of an equivalent white diamond.” (Source:

Slated to close in 2020, the Argyle mine has only a few more precious years left of mining, meaning that owning an Argyle pink diamond can be like holding a piece of history in your hand.

The pink diamonds that come out of the Argyle Diamond Mine display an array of extraordinary pink hues that are synonymous to this particular mine. This is due to the significant boron trace elements that were present during a diamond formation process billions of years ago. They are considered to be ‘jewel-toned,’ with purplish pinks, orangey pinks and some rare reds, which in some circles are considered to be highly saturated pinks.

Owning a pink diamond, however, doesn’t necessarily mean you must own an Argyle pink diamond. Pinks from other countries such as Brazil and India exhibit stunningly pure pink hues. These pinks are often referred to as “bubble-gum pink” and “petal pink,” and they are as equally stunning as Argyle pink diamonds. Some argue that they are even more rare than Argyle pinks because there are so few pink diamond discoveries each year, particularly stones that are over 1 carat.

The Four Cs

In the 1940s, the Gemological Institute of America (GIA) developed “The Four Cs” to provide a universal system for comparing and grading diamonds. Today, the Four Cs — Color, Clarity, Cut and Carat Weight — are an internationally recognized and accepted method for describing and grading diamonds.

With natural fancy color diamonds, one must take color as the primary consideration above all else. It is the color that determines the value of a natural fancy color diamond. This is as opposed to white diamonds, in which case other value factors — clarity, cut or carat weight — may take precedence over color and be the determining factor of the diamond’s value for an individual. Guildhall Diamonds Inc. seeks only pink diamonds in Fancy, Intense and Vivid color grades in tandem with high-clarity grades.

It is particularly rare to find Flawless or Internally Flawless pinks due to the chemical and structural properties in which the color was created during formation. Nonetheless, finding the best clarity possible will help ensure a long-term growth in value. Clients will generally find VVS and VS diamonds in the collection at Guildhall Diamonds Inc.

Diamond clarity is evaluated through a jeweller’s loupe with 10x magnification. Diamond graders look for external characteristics called blemishes and internal characteristics called inclusions, which will have a varying impact on a diamond’s structural integrity, light performance and beauty. There are 11 clarity grades that range from Flawless to Included.

F  Flawless
IF  Internally Flawless
VVS1/2  Very, Very Slightly Included
VS1/2  Very Slightly Included
S1/2  Slightly Included
I 1/2/3  Included

Cut refers to the shape of a diamond and the way in which a diamond has been fashioned. Many diamond shapes (referred to as “cuts”) can maximize color. The finish and make of a diamond brought out by cutters and polishers will express the beauty and light within the diamond. Speak to your diamond specialist about the best cuts that will bring out the most value in your selected stone.

Pink diamonds, particularly Argyle pinks from Australia, are typically smaller in carat weight than other natural fancy color diamonds, but due to their rarity they generally cost significantly more than yellow diamonds of the same carat weight and color grade. There is, however, a minimum carat weight that a pink diamond must meet in order to be considered valuable.
