Though highly sought after by those in the know, many customers are unaware of pink diamonds and what sets them from their white counterparts.

Continue reading to learn more about the grading and quality criteria for pink diamonds if you're considering purchasing one. The purchase criteria for fancy-colored pink diamonds are very different from those for white diamonds. Buying a diamond, any diamond is a challenging process because of the enormous sums at stake—sums that are bigger in pink diamonds—and the minuscule alterations in the diamond that might lead to a significant price shift.

However, the work may be fairly difficult given that most diamond purchases are made for engagement rings, which is a deeply emotional transaction.

What is a Pink Diamond?

Pink is a delicate and charming hue that generally denotes love, romance, and femininity; its lighter tones signify tenderness, while its deeper tones signify passion and vigor. A diamond of this hue is unquestionably the ideal present for any woman who is cherished. We are reminded of peace, kindness, and purity when we see pink in nature, such as on cherry blossoms and rose bushes in the spring. The pink color represents genuine friendship, unwavering unity, and pure affection that doesn't want anything in return. The hue pink represents harmony between the spiritual and the physical in the spiritual realm and calms our mental and emotional turbulence.

Pink diamonds are fancy-colored diamonds with a pink undertone. Pink diamonds' color is not the result of chemical impurities, unlike other fancy-colored diamonds. In contrast, it is not known how pink diamonds are made.


The Argyle diamond mine in Western Australia used to be where pink diamonds were most frequently discovered (now closed after 37 years of operations). Pink diamonds have also been produced in India, South Africa, Brazil, Russia, and Canada. Aside from red diamonds, the pink diamond is one of the rarest types of colored diamonds that are known to exist. Pink diamonds are extremely rare, making them extremely precious. A pink diamond of exceptional quality and rich hue can cost up to $700,000 per carat.

The category of colored diamonds includes pink diamonds. Unlike "ordinary" colorless diamonds, these diamonds come in a range of hues and tints. These colors include the well-known brown and yellow diamonds, less frequent hues like orange, blue, purple, red, and green, as well as our favorite pink. Pink diamonds are quite uncommon. They are among the niche's rarest hues. The origin of colored diamonds' other colors is well understood, but the pink hue is still somewhat of a mystery. 

Natural pink diamonds are among the most uncommon members of the fancy color diamond family, and it is still unclear exactly what gives them their stunning color.

Pink diamonds differ from other fancy diamonds in that chemical impurities do not bring on their color, yet, the precise cause of pink stones is unknown. However, in the field of gemology, the significant extra pressure that these stones experience during their production is most frequently blamed for the pink color of diamonds.

These priceless pink diamonds qualify as "rare" and "collector" stones. Diamond grading colors from reddish purple to orange are called "pink." A difference in tone causes a diamond's pink look, and the color's saturation defines the diamond's color grade. The fancy mild, fancy, and intense grades are most frequently given to pink diamonds.

Value Determining Characteristics

The same four standards used to grade all other gemstones—color, clarity, cut, and carat weight—are also used to grade pink diamonds. The color of a pink diamond is the single most crucial factor in grading it and establishing its worth. However, a pink diamond's value is significantly influenced by its size. A pink diamond will be worth more if it is bigger and has a superior hue. The Pink Star diamond, the most vivid pink diamond in the world at 59.60 carats, is the most well-known pink diamond. Its auction buyer could not pay the agreed-upon amount and was thus forced to default.


The color's hue, saturation, and tone are used to evaluate pink diamonds' color, just like they are with other fancy colored diamonds.

The terms "hue," "saturation," and "tone" all relate to the distribution of color, the main and secondary colors, respectively. Pink can be a modifying color in other diamond colors, but pink can also be found in diamonds in shades ranging from brown-pink to purple-pink. The only secondary colors in pink diamonds are brown, orange, and purple. However, pink diamonds can sometimes display brown and orange overtones simultaneously, giving them the nickname "brownish orangey pink" diamonds.

Although purple-pink diamonds are sometimes held in extremely high esteem, pure pink diamonds are typically thought to be the best type of pink diamond. A vibrant pink diamond will often be worth more than a bigger, lighter pink diamond. However, this isn't always the case. Pink diamonds come in various intensities, including faint, very light, fancy light, fancy pink, fancy intense, fancy vivid, and fancy deep/dark.

The more intense pink diamonds are significantly rare, the less vivid, just like any fancy color diamonds, which is part of the reason they cost more. Depending on the specimen, the same natural cause—the progression of the pink in pink diamonds—can be more or less intense. The most concentrated diamonds in each hue are extremely difficult to discover. Even though the GIA maintains a master inventory of every diamond color, there isn't a complete agreement on what constitutes each color intensity grade. As a result, a subscale of 1–10 is also present for each color intensity.


To assess the purity of each diamond, a loupe is used. Using a 10x magnification, it is possible to see if the diamond has inclusions inside or on the surface. Similar to other diamonds, the clarity of pink diamonds is graded on a scale from Flawless to Included. Similar to the rest of the hues of fancy-color diamonds, the clarity has minimal bearing on a pink diamond's value. Only 7% of pink diamonds are either Flawless or Internally Flawless (IF), while the majority are Slightly Included (SI). Since pink diamonds are created when the lattice structure of the stone is deformed, the likelihood that they will be of low clarity is higher, making excellent clarity pink diamonds exceedingly rare (7%).

It is advisable to comprehend the range of available clarity levels and choose the one most suited for you, even though the clarity aspect becomes less significant when it comes to uncommon and distinctive hues like pink. The price difference between a fancy pink diamond with a VVS1 clarity rating and one with a VVS2 clarity rating is also negligible. But the price variations considerably widen when traveling across level groupings, such as between VVS, VS, and SI.

Due to the relatively cheap price for such a rare stone, selecting a diamond with a low level of clarity might be advantageous. However, it is advisable to pick a degree of clarity with faults that the human eye can't detect to ensure light's magical brilliance and penetration.


Although many people confuse carat with size, it refers to a measure of weight—0.2 grams to be exact (or 100 points)—while the diamond's shape and cutting technique impact how big a diamond seems to be. Weight makes a significant impact when it comes to rare gems like fancy colored diamonds in general and fancy pink diamonds in particular. With weight, a diamond's price rises tremendously. For instance, a single 1-carat pink diamond with the same color, clarity, and cut will cost $30-$40K, but 100 pink diamonds weighing 0.01 apiece (1 carat total) will cost $2,000-$2,500. 


Though the cut is a much more intricate element, we naturally consider the diamond's form when thinking about this characteristic. The quality of the diamond's cut, polish, and symmetry as a high, medium, or poor grading, and how the diamond polisher molded the diamond into the raw crystal. A fancy colored diamond that has been expertly cut will enhance its colors, produce mesmerizing light reflections, and do all possible to showcase its benefits and raise its worth.

Choose your chosen grade depending on the appearance of the diamond because a beautiful cut makes the stone seem stunning. However, it would be a shame to accept a lesser quality cut that is unflattering to the timeless diamond that you or your loved one will preserve and treasure for the rest of your lives and lacks symmetry or brilliance.

The distribution of color of the diamond is a factor to consider while selecting the ideal pink diamond for you. Occasionally, concentrations of hues are created unevenly in different parts of the diamond during the protracted chemical process that generates the diamond crystal over many years. Naturally, a diamond's hue will be richer and deeper if the color is distributed evenly.

The Rarity of Pink Diamonds

Natural pink diamonds are extraordinarily valuable because they are so uncommon. There has been a genuine worry that pink diamond mine supplies have been limited until recently. However, those worries have been eased, at least until 2020, owing to the opening of a new mine in Western Australia. However, the search for marketable pink diamonds is so laborious that just one carat of a marketable fancy pink diamond is found for every million carats of raw diamonds that are mined.


Pink diamonds are extremely hard to find. Only 0.01% of the roughly 14,000,000 carats worth of diamonds that are mined, polished, and sold each year are colored diamonds, and of them, only 0.0001% are pink diamonds. A year's worth might fit in the palm of your hand with such uniqueness.

All these reasons and more make pink diamonds extremely sought-after and well-liked among collectors who want to add the rarest and most distinctive diamonds to their collections and investors looking for chances to invest in a rare asset with a high and steady value that rises over time. They can accomplish so brilliantly with fancy pink diamonds.

Pink diamonds stand out from other diamonds because of their vivid hue, which makes it simple to tell them apart from diamonds of other colors. Some individuals might believe that pink diamonds are unique, stronger, or more durable than white diamonds or diamonds of other hues.

Collectors who couldn't resist the stone's beauty and appeal have recently purchased extremely rare pink diamonds for extravagant sums. An emerald cut fancy vivid pink diamond weighing 24.78 carats was acquired for a record price of $45.6 million by London jeweler Laurence Graff, who has a fondness for unusual and exquisite stones, at an auction in 2010.

Pink Diamonds: Why Are They Pink?

Since experts are unsure of the specific reason why pink diamonds have that hue, there is no clear-cut solution to this query. According to certain suppositions and educated assumptions from gemologists, the pink hue these diamonds are renowned for and prized for results from the even greater pressure they endure throughout the formation process beneath the ground.

All diamonds are created under this pressure, but pink diamonds are created under significantly more strain. We'll now examine the research supporting the assertion that pink diamonds are made pink by the same pressure and heat that create them. After the diamond is generated in the earth, extreme temperatures and tremendous pressure, also known as non-isotropic stress, from all directions, cause the diamond lattice to distort and result in this hue.

Due to this deformation, numerous carbon atoms are displaced from their original places, which also affects the diamond's ability to reflect light. Because of this specific chemical configuration, you can observe that the stone is pink. Since pink diamonds frequently originate in far harsher environments than these, gemologists and other scientists speculatively believe that pink diamonds' pink color results from these harsher environments. Remember that the rarest type of diamonds is those that are pink. Therefore, original diamonds from a reputable and licensed diamond dealer are preferable for you regarding the pinkness of your diamond.

The origin of the pink diamond's hue remains a mystery to gemologists. Pink diamonds do not contain the impurities that give them their color, unlike other stones in the family of fancy-color diamonds. Several hypotheses have been put forth regarding the cause of the diamond's distinctive color. Some believe that the intense pressure pink diamonds experienced during their development is the most likely culprit, while others think it could be connected to a seismic event that affected the stone's molecular structure. The world now has access to a stunning stone for engagement rings, bracelets, and earrings, even if the precise reason for the pink diamond's hue is still unclear.

Pink Diamond Cost

Given that pink diamonds are among the rarest gems on Earth, you all presumably assume their uniqueness comes with a price, and you're correct. The reputation that goes along with pink diamonds is that they are uncommon and simple to locate and purchase if you're interested in one.


Your jeweler or diamond dealer will thus increase the price as much as possible solely because of the rarity aspect, even though those pink diamonds are identical to other diamonds, omitting the color component because they are aware of this reality. Because people know these diamonds are valuable and uncommon, they are exceedingly difficult to discover but quite simple to sell because they are likely to be purchased as soon as they come into contact with one. 

Let's look at some data now to determine the outcome. After that, we'll talk about whether or not you should consider purchasing one of these gems. The depth and level of intensity of the pink hue have a significant impact on the price of a pink diamond. A pink diamond with a deep pink tint that is easy to discern may easily go for up to $700,000 on a bad day or can even reach a million dollars if you're buying one of the nicest pink diamonds out of there. A light pink diamond can cost as little as $12,000 if it weighs a carat. It highlights how reliant a price tag is on certain factors, such as color. The diamond's cut and the region of the world you are purchasing it also have a significant role. Don't worry; we'll look at the diamond's cut and possible settings later. Pink diamonds may be found in a variety of settings. But let's concentrate on the cost for now.

Due to their extreme rarity, pink diamonds command exorbitant prices; as a result, you won't find a pink diamond that is tougher, more resilient, or endowed with any other "special traits" than the hue. When a 1-carat diamond costs more than $500k, you know you're spending a lot of money. That is the major "gist" of these gems, and their sellers know that you are aware of their rarity. In other words, if you're not purchasing a pink diamond just for its color, you'd be better off spending less money on several smaller diamonds or larger gemstones.

You will need to pay any fees if you want to bring a pink diamond back into the US or another continent. If you want to buy a pink diamond in Europe, expect to pay roughly $220,000 only for the diamond. A 0.40-carat fancy deep pink round cut diamond from the continent of Africa, which is renowned for having had the most diamonds discovered there, costs around $40,000.

This may appear to be less expensive than the ones we've discussed, and it is, but you must remember that the diamond we discussed was more than twice as large as the 0.40-carat diamond that we are currently evaluating. So, the situation is much the same everywhere, and the prices are comparable. The only differences are whether you will incur additional costs and the size of your pink diamond.

The GIA developed the 4C's diamond grading and evaluation method many years ago. Carat, Color, Clarity, and Cut are these. These are the four major 4 characteristics that can give you a broad idea of the diamond's worth and its pricing, even though there are many more characteristics that can significantly impact the diamond's price. Put, a colorless diamond with intense fluorescence—which isn't even one of the four Cs—will be readily valued 15%–20% less than a comparable stone without fluorescence. The 4Cs were, however, primarily developed by the GIA for colorless diamonds.

The hue of colored diamonds receives the most attention. A fine fancy pink weighing 1 carat will be much more expensive than a pure bright pink weighing 1 carat (or even 2 carats for that matter). You should be aware that prices increase with the strength of the hue, even if there is no set formula for how much an intense pink would cost over a fancy or a faint. And occasionally, when we approach the greatest intensities, the growth is exponential rather than linear (in multiplies).

Reasons to Take Precautions When Purchasing Pink Diamonds

Let's discuss the dangers you should be aware of when purchasing pink diamonds while we're on the subject of (over)pricing pink diamonds. As we've already discussed, some will sell you tempered diamonds that seem pink but aren't pink or outrageously overprice pink diamonds.

Even worse, they could try to sell you phony pink diamonds, but con artists like these are aware of the amount of money at stake and that, barring transactions on the black market, you will likely test stones before making a purchase. To avoid being duped into purchasing an expensive diamond or a diamond that doesn't have a hue that is deep and vivid enough to be labeled a pink diamond, we'll look at a few characteristics you should be aware of before you go pink diamond shopping.

First of all, the overpricing. Diamond merchants frequently convey a feeling of urgency when selling these items for two reasons. The first explanation is that they are aware that anyone looking to purchase pink diamonds would probably act quickly and do so. This is extremely important for the sale of the diamond since the seller will almost certainly convey a feeling of urgency by showing proof that they have other serious purchasers and that if you don't buy it now, it won't be possible later. 

People frequently fall for this because they don't care if they overpay by a few thousand dollars since they believe the gems are valuable. Knowing that the pink diamond isn't the only one on Earth and that another opportunity will present itself if you miss the chance to purchase that particular, exorbitantly expensive diamond is crucial in these circumstances (probably with a better price).

Dealing with dishonest or dubious diamond sellers who want to sell you a "pink diamond" that is significantly less expensive than a genuine pink diamond while using the justification that the diamond lacks legal documentation is the second thing you should be wary of. Our best recommendation in these circumstances is to take your money and go since these people either offer phony diamonds that you frequently don't even have the chance to examine or sell real gems obtained illegally. These people frequently try to sell the gems as quickly as possible to get rid of them. Congratulations—you now have an illegal diamond if you fell for this.

Lastly, be wary of jewelers and diamond dealers who attempt to sell you on the idea that light pink diamonds are worth the exorbitant price tag that hangs from their box. You shouldn't pay tens of thousands of dollars merely for your "pink" diamond to be pale and appear like other diamonds; light pink diamonds are almost as expensive as ordinary diamonds.

All of these circumstances are quite detrimental to the buyer. Therefore, our strong recommendation is to continue looking for pink diamonds only in establishments with protected and certified gems. Also, remember that you don't have to spend too much for a diamond immediately; allow yourself some time.

Rarest Diamonds with Millions in Value

In addition to being alluring and magnificent, pink diamonds are one of the rarest stones in the world, second only to red diamonds. Its existence makes it more unique and well-liked among collectors, investors, and jewelry fans. It is still a mystery to the world because of its form, geometry, and color, and it appears highly intriguing due to its rarity and mystifying natural pink shade. 

In addition to being unquestionably magnificent, pink diamonds' high value is due to their great rarity. Pink diamonds have traditionally been prized by royalty and are currently projected to sell for millions of dollars per carat due to their enormous carat weights and scarcity of vibrant hues. You might not be aware that pink diamonds cost 20 times as much as white diamonds. Astonishingly, a one-carat pink diamond might cost between $100,000 and $1 million. 

Even experts disagree on how or why exactly these specific diamonds are colored this way since the natural color saturation of pink and purple colors inside them is produced by such an uncommon and rare method. All diamonds begin their lives under extreme pressure deep under the earth's mantle. Diamonds are transported to the earth's crust by molten lava. All diamonds go through this process, but pink diamonds appear to go through a special geological process that puts too much stress and strain on the crystal that has already formed.

Only a small number of countries have discovered pink diamond mines. More than 90% of the supply of natural pink diamonds in the world is produced from the renowned Argyle Mine in Western Australia, which is located there. India, South Africa, Canada, Russia, Brazil, and Argyle were formerly known to contain them. The Argyle mine only produces less than 1% of the world's pink diamonds, which are the rarest of the rare. This is noteworthy because just one carat of pink diamonds is available for sale for every million carats of raw diamonds mined in Argyle.

Pink Diamond Buying Guide: Key Takeaway

The major determinants of a fancy color diamond's price are color intensity and carat weight, and fancy pink diamonds are no exception to this rule. Secondary modifying hues like Orange, Brown, Purple, and Red can exist when pinks are present. These hues can occasionally be so faint that they are invisible to the unaided eye. An intensely colored pink diamond will be more expensive since they are highly uncommon and have no secondary or overtones.

Some exceptional stones, like the Mystra, a 2.02 ct Fancy Vivid Purplish Pink round. The Mystra's combination of carat weight, intensity, cut (rounds are extremely uncommon shapes for a fancy color), and Purplish overtone makes it one of the most uncommon pink diamonds. Pink diamonds are widely regarded as very wealthy jewelry. Pink diamond prices have dramatically increased due to their increased rarity and desirability. As a result, they are frequently included in investment portfolios as great alternative investments. In general, collectors prefer Type II diamonds, which include pink diamonds.

The hue of a pink diamond should always be prioritized while purchasing. The final value of a pink diamond is determined by its carat weight, color, and intensity. Due to the high rarity of fancy colored diamonds, clarity and cut aren't as crucial. Most pink diamonds have SI clarity and frequently have eye-clean surfaces. Due to the great rarity of pink diamonds, even I1 gems are highly prized.
