What You Need to Know About Rare Pink Diamonds

Rare pink diamonds are highly sought-after at this time and age, especially since the world-renowned Argyle diamond mine in Western Australia (which produces over 90% of the world’s pinks) is scheduled to close in 2018. It comes as no surprise that the steadily dwindling supply of pink diamonds is driving demand to an all-time high. Nearly everyone wants a piece of the pink stone for one of many good reasons: they are incredibly and exceedingly rare, according to Argyle mine statistics. As a result, these pink rarities are prohibitively expensive.

Rare Pink Diamond Qualities

If you are a fellow diamond enthusiast with a growing passion and appreciation for this rare breed of diamonds, here is everything you need to know about the pink variety:

Color: The majority of fancy diamonds owe their distinct hues to the presence of trace elements ranging from nitrogen to boron. A fancy pink diamond, on the other hand, acquires its vibrant color due to an atomic level lattice defect referred to as plastic deformation. However, scientists have not fully uncovered how pink diamonds attain their unique hue. Color plays a leading role in determining the price range of a pink diamond, and we will further elaborate on this in the succeeding bullet points.

Tone: The tone of a pink diamond refers to its lightness or darkness of its real pink hue and the continuum in between. The Gemological Institute or GIA grading does not make a distinction in tones, but to the naked eye, a diamond with darker tones may appear more intense in color. If you are looking for the appearance of a Fancy Intense Pink Diamond without the price tag of one, a great option may be a Fancy Pink Diamond with a darker tone.

Intensity: Pink diamonds are assessed according to the color intensity or the combination of tone and saturation. The more intense a gem’s color saturation is, the more valuable it is. For instance, a Fancy Intense Pink Diamond will be worth so much more than a Fancy Pink. That said, apart from immensely saturated pinks, gemstones with secondary color modifiers such as pinks with hints of vibrant purple are very rare collectors’ items that may fetch millions of dollars per carat.

Secondary Color Modifiers: Carat weight and color intensity are the most significant influencers of a color diamond’s price, especially for fancy pink stones. Secondary modifying colors such as purple, orange, brown, and red can be present in pink diamonds. Sometimes, the presence of such colors is so subtle that they are barely noticeable to the naked eye. A fancy pink diamond with no secondary color or overtone is exceptionally rare. The more intense the color is, the more the stone will be worth.

Fluorescence: It is quite common for pink diamonds to display fluorescence. As a matter of fact, finding a genuine pink diamond without a fluorescent quality is rare. Thus, its presence usually does not impact the price. According to GIA, more than 80% pink diamonds exhibit some degree of fluorescence. During the final analysis, the enhancement of a gemstone’s aesthetics that fluorescence offers is entirely subjective.

Clarity: Because of the rarity of a fancy pink diamond, clarity plays a smaller part in their value than it does in yellow diamonds. According to GIA, roughly 7% of pink diamonds attain a clarity grade of Flawless or Internally Flawless, whereas nearly half are either Slightly Included or Included. Color is a far more significant determinant of a pink diamond’s valuation, alongside rarity.

Shape: It well-known that round cuts tend to produce lower color saturation. In the case of pink diamonds, like other colors, they are generally cut into fancy shapes such as emerald cuts, princesses, cushions, and so on. Round cuts can cause color desaturation because they exhibit the best reflecting white light, which also gives them their sparkle. When a pink diamond is given a round cut, it may result in the pink color appearing much fainter, whereas a fancy shape, which reflects significantly less white light, will maximize color saturation. It is also important to take note of uneven color distributions as well, which will be noted on your GIA certificate since they can affect a pink diamond’s overall appearance and value.

Value: Pink is under one of the rarest color categories in the fancy color diamond universe. Unlike rare yellow diamonds, which still comprise over 60% of all fancy color diamonds produced, natural pink diamonds fall into the same category as reds and blues for their extreme rarity. Because of the pink’s striking color and constraints on supply, they present excellent investment opportunities. The value of pink diamonds has been steadily increasing for years. If you are considering a rare pink diamond as an investment opportunity, make sure to choose gemstones with much more profound color saturation with a relatively large size that fits your budget. Remember that the most reliable determinants of pink diamond rarity and value are color, size, shape, and clarity in that exact order. Pink diamond prices may vary based on these qualities. In case you stumble upon a round cut Fancy Vivid Pink Diamond — which is an extremely rare shape for a fancy color diamond — and it happens to be only 0.30ct and Slightly Included, it may be an exceptionally rare and incredibly valuable specimen.


Pink diamonds are not only rising in demand and popularity, but they are also rarer than ever. Throughout history, pink diamonds have been treasured by royal families, with the most notable being the Williamson Pink — a spectacular 23-carat diamond that is currently in possession of Queen Elizabeth II. Even Hollywood celebrities such as Jennifer Lopez, Mariah Carey, Blake Lively, and Kate Bosworth are known to have pink diamonds. However, they tend to be quite large and faint in color. An authentic Argyle pink diamond offers an intensity of color that is unmatched by any other pink diamond around the world, thus, their value.
