100 Carat Pink Diamond Price (All You Need To Know)

100 carat pink diamond price

Very few diamonds have ever been found that are truly colossal in size, and even fewer large stones are found in fancy colors.

These are some of the rarest gemstones in the world and, as such, they sell for incredibly high prices.

Most diamonds at this size are still in their rough state, but a few cut diamonds of around 100 carats have been sold. The largest cut pink diamonds, however, are around 60 carats in weight.

Read ahead to find out all about the price you might expect for particularly sizeable pink diamonds.

Are Pink Diamonds Real?

One of the first questions that most people have about pink diamonds is what kind of gemstone they actually are.

It is easy to think that pink diamonds could be a nickname or a misnomer, but you might be surprised to find out that these spectacular stones are genuine diamonds in every sense of the word.

They are part of a subgroup that is usually referred to as “fancy color diamonds”, which encompasses a wide and mesmerizing variety of different colors.

Colored diamonds can be found in pink, red, yellow, blue, green, brown, gray, black, and many other colors as well.

How Much Are 100-Carat Diamonds Worth?

While most small diamonds have a relatively predictable price based on their qualities, large diamonds are in a world of their own.

These stones have a lot of worth simply due to their remarkable size, particularly once they have been cut.

Though it is not too uncommon for rough diamonds to be discovered that weigh 100 carats or more, seeing a cut diamond of this size is very rare indeed. In fact, only a few 100-carat or more cut diamonds have ever been sold.

Let’s take a look at some of the 100-carat cut diamonds of the world, and just how much money they managed to make at auction.

Carat WeightPriceYear Sold
100$22 million2015
100.94$14.1 million2021
101.73$26.7 million2013
118.28$30.6 million2013
163.41$33.7 million2017

So if you are on the lookout for a 100-carat plus diamond, then you can expect to pay anywhere between 20 and 40 million dollars to get your hands on one.

There have been some much larger diamonds that have made their way onto the market, but most of these have still been in their rough state.

The majority of the largest cut diamonds in the world have never actually been sold, but they are still very highly valued.

What Are The Largest Pink Diamonds In The World?

If you’re particularly interested in large pink diamonds, you might be surprised to find out that these are among the most expensive gemstones of all time, even for significantly smaller examples.

There have been some rough pink diamonds that have been found weighing more than 100 carats, like the Lulo Rose which is estimated to be around 182 carats in weight.

When it comes to those that have been cut and shaped, however, around 60 carats is the biggest.

The price of some of these pink diamonds is astronomical. In fact, the most expensive diamond that has ever been sold at auction was pink: The Pink Star.

Graff Pink24.78$46 million
The Princie36.45$39.3 million
Sweet Josephine16.08$28.5 million
The Perfect Pink14.23$23.2 million

Based on what we’ve seen from the large pink diamonds that have been sold around the world, you could expect a 100-carat cut pink to fetch more than any other diamond that has ever been purchased – likely at over $100 million.

What Affects The Value Of A Pink Diamond?

Although carat weight is certainly one of the main deciding factors for the price of a pink diamond, there are a number of other things that need to be taken into consideration as well.

The origin of the stone will greatly impact its value – particularly if it has been lab-grown rather than mined – and the other three “Four C” categories are also highly important.

  • Color: Every diamond will be assessed by its color, but this is particularly significant for pink diamonds. They will be given a descriptor based on how intense the pink coloring is, ranging from “Faint” to “Vivid” or “Intense”.
  • Clarity: The number of inclusions and/or blemishes inside and outside of a diamond will affect its clarity. The clearer a stone is, the more it will be worth.
  • Cut: How well a diamond has been cut has an impact on more than just its shape and style. This measurement will also tell you how bright and vibrant the stone looks, and how much light it reflects.

All of these different considerations are why it is so difficult to pinpoint the exact value of an individual stone.

Not to mention the fact that sizeable specimens often have a history that makes them even more desirable and adds to their overall mystique – which therefore influences how much a collector might be willing to pay.

Why Are Pink Diamonds Pink?

What sets fancy color diamonds apart from regular colorless stones is simply their color, and this can be the result of a number of different influences.

Sometimes, it can mean that there are minor additional elements within the stone (like boron that gives a blue color), a high number of inclusions (like graphite that can turn a stone black), or exposure once the stone has finished growing (like radiation, which makes a diamond green).

One of the reasons why pink diamonds are so fascinating is that the origin of their color is still unknown to this day.

The most popular theory is that a certain type of shear pressure causes the molecular structure of the stone to deform as it travels through different layers of rock under the earth, and this is what makes them appear pink.

How Rare Are Pink Diamonds?

Whatever the true cause of the pink color in diamonds might be, it is certainly something that is very particular and hard to come by.

There are only a few locations around the world where natural pink diamonds have ever been uncovered and, even at these sites, they are particularly rare.

Pink diamonds are actually considered to be the rarest color variation in the world, besides one. Only red diamonds are more difficult to come by, and many people believe that these are really just very intense examples of pink diamonds.

It is estimated that less than 1% of the world’s diamonds are naturally colored, and less than 1% of these will be pink.

Even the mine that is responsible for around 80% of all the world’s pink diamonds – the Argyle Mine in Western Australia – only found a very limited number.

Of the 20 million carats that they used to discover in a year, around 0.1% were officially graded as pink. What makes these stones even rarer now is that the Argyle Mine closed down in 2020.

Diamond Carat Weight

The “carat” of a diamond is simply a measurement of the stone’s weight, and one carat weighs the same as 200 milligrams – or 0.2 grams.

This can be a little deceptive, as some people take this measurement to mean size, but this is not the case. For example, a 2-carat diamond will weigh twice as much as a 1-carat diamond, but it will not be twice as large.

A diamond’s carat weight is one of the “Four Cs” of diamond grading that determines the overall value of the stone.

When you’re talking about a diamond variation that is as rare as this, the idea of uncovering something that is a considerable size becomes even more unlikely.

While fancy yellow diamonds are found relatively regularly (making large discoveries much more common), pink diamonds larger than 1 carat are few and far between.

In the truly massive range of around 100 carats, there are an extremely limited number of diamonds of any kind at all.

So, what price would a 100-carat pink diamond go for? Though there are some rough examples out there, a cut pink diamond of this size has never been sold.

Looking at how much large pink diamonds tend to sell for; however, you could expect a 100-carat example to reach a higher price than any other gemstone that has ever been put on the market.

A 100-carat cut pink might even be worth more than $100 million.
