What Is A Red Diamond?
Most people assume that all diamonds are either white or colorless, but a few rare stones can actually develop in a huge variety of different colors.
These are generally referred to as “fancy color diamonds”, and they are often highly valuable.
Although red diamonds might be mistaken for other red gemstones to the untrained eye, like rubies, agates, or garnets, they are actually a unique color variation of genuine diamonds.
They are considered as much a diamond as any other, but their red coloring makes them stand out significantly from the crowd.
Fancy color diamonds can be found in red, blue, pink, purple, brown, green, orange, yellow, brown, gray, black, and almost any color you can imagine in between.

How Do Red Diamonds Get Their Color?
One of the fascinating things about colored diamonds is that almost all of their unique colorings come from different causes.
Some fancy color diamonds receive their color due to high numbers of inclusions within the stone or the presence of trace elements in the crystal structure, others develop a hue as a result of certain pressure or temperature conditions during their formation, and others change color after they have grown due to outside influences like radiation.
What causes a red color in diamonds, however, has not been officially determined. Just like with pink diamonds, there is a significant amount of debate as to what makes these diamonds red, which is made even more complicated and mysterious by how few of them have ever been found.
The most popular theory for the origin of the red color is that certain types of pressure lead to plastic deformation, displacing some of the atoms within the lattice structure and causing such a strong coloration to appear.
This is actually the same process that is believed by many to result in pink diamonds as well, which is one of the reasons why these types of color diamonds are often thought of as highly linked – if not just different intensities of the exact same color.
Red Diamonds Price
To truly understand how much these stones are worth, we can take a look at how much the few examples that do exist tend to sell for.
|Red Diamond Carat||Price|
|0.2-carat||$200,000 – $400,000|
|0.5-carat||$400,000 – $500,000|
|0.7-carat||$600,000 – $800,000|
|0.9-carat||$700,000 – $900,000|
|1.0-carat||$800,000 – 1,000,000|
Of course, it is very difficult to say exactly how much a red diamond will be worth based on its carat weight alone, as there are many other factors that can influence its value.
How Much Are Red Diamonds Worth?
Due to the fact that they are so incredibly rare and beautiful, red diamonds are the most expensive variation of the stone that exists. In fact, they are one of the most valuable gemstones on the planet by weight.
It is difficult to find them at any significant size, however, and there aren’t many that weigh more than one carat. For such small stones, they certainly have a large price tag.
Typically, red diamonds sell for hundreds of thousands of dollars per carat, which is significantly more than you would expect to pay for a diamond of any other color.
What Makes A Red Diamond More Expensive?
Just like with regular colorless diamonds, the price of a red diamond is determined by its features. There are four major characteristics that are assessed, known as the 4 Cs: Color, Clarity, Cut, and Carat.
- Color: For a diamond to be considered red, then it needs to achieve a color grading of Fancy Red.
- Clarity: This is about how clear a stone is, and it refers to the number of inclusions or blemishes that can be seen under a microscope.
- Cut: How a diamond is shaped and the quality of the facets cut into it will affect how bright it looks and how well it reflects light.
- Carat: This is simply the weight of the diamond, and 1 carat is equal to 0.2 grams.
There is one other factor that greatly influences how much you can expect to pay for a diamond, and that is its origin.
Lab-created (or lab-grown) diamonds are much more affordable than those mined directly from the earth, particularly when it comes to such a rare color as red.
What Shades Of Red Diamonds Are There?
Most fancy color diamonds are graded on the intensity of the color that can be seen, from faint to light to intense or vibrant.
Red diamonds, however, only appear in one intensity: a very deep and rich shade of red described as Fancy Red.
This contributes to the belief that red diamonds are actually just the deepest and strongest possible examples of pink diamonds.
Some polishers have even re-polished Fancy Deep Pink diamonds to the point where they have managed to achieve a GIA grading of Fancy Red.
Rather than intensity, these stones are therefore assessed based on their hue and saturation. Other secondary colors are often present, so the color of red diamonds will generally be referred to as brown-red, orange-red, or purple-red. Interestingly, red is never a modifying color for other diamonds in the same way.
How Rare Are Red Diamonds?
If diamonds are rare, then red diamonds are on a whole different level. This color variation is considered to be the rarest of them all, and very few examples have ever been found.
In fact, between 1957 and 1987 the GIA did not award a red grade to any diamonds at all, and official records state that only about 30 of true gem quality have ever been mined.
This is partly due to the fact that most diamonds with some red colorings are actually qualified as intense pink diamonds, rather than being truly red.
That’s not to say that there are only about 30 red diamonds in the world. Lab-created diamonds can be given a red or pink color through a multiple-treatment process that involves both irradiation and annealing, though these stones are much less valuable than those that occur naturally.
Where Do Red Diamonds Come From?
Almost all of the red diamonds that have ever been found were discovered in the famous Argyle diamond mine in Australia.
There are, however, a few other mines in places like Africa, Russia, and Brazil that have unearthed these treasures.
The first red diamond on record was actually found by a rancher from Montana in 1956, who sold it in 1987 for nearly $1,000,000.
Another link between red and pink diamonds is that they are often found in the same sort of locations.
The Argyle mine, in particular, was very well-known as the source of most of the world’s pink diamonds, before it was closed in 2020.
How Do You Know That A Red Diamond Is Genuine?
Whether the diamond that you are looking at was mined from the earth or created in a lab, it will still be one of the most expensive purchases that you will ever make, so how do you know that it’s the real thing?
Well, it’s all to do with the grading process. Every diamond (but particularly those with higher value) should be evaluated and graded by an independent laboratory, where expert gemologists will examine it and confirm its characteristics and quality.
These labs will issue a certificate, or some other form of official paperwork, which will go into great detail about all of the individual features of the stone and validate its authenticity.
You should always make sure to look at a grading document for any diamond that you buy, but this is even more important when you’re talking about red diamonds.
Because so few diamonds achieve an official “red” color grading, you will want to have definitive proof that you are not actually purchasing a strongly-colored pink diamond instead.
What Are The Most Reputable Diamond Grading Labs?
There are many different organizations around the world that examine and assess diamonds, but three of them have the highest reputation and are the most commonly used by jewelers and retailers.
- AGS: The American Gem Society
- IGI: The International Gemological Institute
If your stone is graded by one of these places, then you can be reassured that it is legitimate.

So, what kind of price do red diamonds tend to fetch? A big one. These are considered to be the rarest color variation of diamonds and, as such, they are among the most valuable gemstones on the planet.
Per carat, they will sell for hundreds of thousands of dollars, if not more than a million, and there are only around 30 natural examples on record.
You can find more affordable red diamonds that were treated in a lab to give them their red color, and these stones are almost indistinguishable from those that formed in the earth.
