Natural Fancy-Colored Diamonds


When you hear the word diamond, what image automatically springs to mind? The answer for many people will be a clear, almost white, sparkling gemstone. And you would, of course, be correct, but did you know that diamonds are also found in other colors?

Colored diamonds are admittedly a rarity, but they do exist in a vivid rainbow of colors. They are referred to as “natural fancy-colored diamonds,” and it’s easy to see why they are a rarity in the world of gemstones, as only 10,000 diamonds actually possess natural fancy color. That’s less than 1% of diamonds annually graded by the Gemological Institute of America (GIA), which are classified as fancy-colored diamonds, making them the most highly prized of stones.

While natural fancy-colored diamonds have always been highly desired for their rarity, in the last three decades, their popularity has increased dramatically. This can be largely attributed to the Western Australian Argyle mine, which cleverly started to market its brown diamonds in the 1980s using the trade names of “Cognac” and “Champagne,” increasing the appeal of natural fancy-colored diamonds to jewelry buyers. This mine is also responsible for 90% of the global supply of red and pink diamonds.

If you’re considering the purchase of natural fancy-colored diamonds, we’ve compiled a short educational guide to help you understand a little more about these beautiful gemstones and to assist you in selecting the natural fancy-colored diamond that is perfect for you.


Natural fancy-colored diamonds are formed within the Earth’s core by exactly the same process as traditional white diamonds. However, there’s one unique difference that causes the presence of coloration within these diamonds.

Within their chemical composition, natural fancy-colored diamonds exhibit structural defects or impurities caused by the conditions prevailing during the crystallization process when the diamond was first formed.

Foreign particles that become trapped during this crystallization process affect and alter the chemical process, resulting in diamonds with rare and unique colorings and different intensities of these hues.

The Formation Process Of Natural Fancy-colored Diamonds


The different colors of natural fancy-colored diamonds are created by different particulates and trace minerals, resulting in different colors and intensities of color:

Blue and Gray Diamonds

Blue and Gray Diamonds

Natural blue diamonds are a result of the presence of the impurity of boron. Boron bonds to carbon within the crystal structure of the diamond and absorbs the yellow, red and green areas of the color spectrum, creating a blue natural fancy-colored diamond. Many blue diamonds are seen to be modified by a secondary gray tone or saturation that’s uneven, which is what makes highly saturated blue diamonds extremely rare and very desirable.

Pink and Red Diamonds

Pink and Red Diamonds

The colors of pink and red natural fancy-colored diamonds are created by a combination of highly intense heat and pressure whilst these diamonds are buried within the Earth’s core. These two factors work together to distort the structure of the crystal lattice so that when it absorbs green light, this then reflects a pink hue. Red natural fancy-colored diamonds are the rarest of all colors. They are thought to be essentially deeply colored pink diamonds. Whilst very attractive and rare, they are not the most valued of natural fancy-colored diamonds.

Brown, Orange and Yellow Diamonds

Brown, Orange and Yellow Diamonds

Nitrogen is the element responsible for the coloration of brown, yellow, and orange colored diamonds. When the diamond is forming, Nitrogen atoms in its carbon crystal structure arrange themselves in such a way that the blue range of the color spectrum is absorbed, producing a yellow color. Brown and orange coloration is caused by a specific grouping of these Nitrogen atoms that causes absorption of light in both the blue and yellow spectrums. Brown and yellow are the most common of the natural fancy-colored diamonds.

Purple and Violet Diamonds

Purple and Violet Diamonds

It is still unproven as to what factors actually cause the formation of purple and violet natural colored diamonds. However,it’s thought that the presence of hydrogen may be partly responsible for their hue.

Black diamonds

Black diamonds

Black natural fancy-colored diamonds are made up of many tiny black crystals. They are bound together by internal inclusions that hold the tiny diamond particles together – this is known as a polycrystalline structure and is the reason this type of diamond exhibits a dark black color. In addition, unlike colorless diamonds, black natural fancy-colored diamonds absorb rather than refract and reflect light.

Green Diamonds

Green Diamonds

Just as they are about to leave the uppermost layer of the Earth’s crust, green-colored diamonds absorb natural radiation, which causes them to absorb yellow and red light and reflect a green hue that gives them their color.


Natural fancy-colored diamonds are graded and valued by the GIA using the factors of color, tone, saturation, and hue of the diamond. It is the combination of these factors that determines the value of the diamond, with color being the most important attribute.

The first step of the grading process for natural fancy-colored diamonds is to assess the diamond’s “face up” color set against a neutral gray background to determine the basic color of the diamond. Once the color is determined, comparisons to a representative color are made using defined color space areas split into boxes. The natural fancy-colored diamond is placed in one of the boxes to identify the color characteristic that most closely matches that of the stone. The diamond is then color-classified according to the description of the color space it sits within.

Hue, tone, and saturation are also used in grading natural fancy-colored diamonds. Hue is the primary color of the diamond, with the GIA identifying 27 hues, each of which has a range of color possibilities. Tone is the definition of how light or dark the hue is, and saturation is the intensity of the diamond’s coloration.

Nine grades are used within the GIA color grading system for natural fancy-colored diamonds. These are:

  • Fancy Vivid

    Fancy vivid diamonds are the highest grade and contain the most intense color saturation. These stones will usually have a very vibrant hue that stands out in any setting. They are also rare, so finding one can be difficult. However, these stones are highly sought after and can be very valuable investments.

  • Fancy Intense

    Fancy intense diamonds come in second place when it comes to color saturation and intensity. Though they may not be as striking as fancy vivids, they still make excellent investments due to their rarity and beauty.

  • Fancy Deep

    As the name implies, fancy deep diamonds contain deeper hues than those found in lower grades, such as Fancy Light or Light. While these stones may not have the same vibrancy as other grades, they still make beautiful centerpieces for any jewelry piece or collection.

  • Fancy Dark

    These diamonds have a deep and dark color tone but still contain enough color saturation to qualify as a fancy diamond grade according to the GIA grading system. They are often used for accents or side stones in jewelry designs due to their unique look.

  • Fancy

    The fancy grade is the middle ground grade for fancy-colored diamonds. They do not have the same intense color saturation as the highest grade but still have a lot more of a hue than the lowest.

  • Fancy Light

    As opposed to fancy vivid or intense diamonds, fancy light diamonds contain less color saturation but still retain some vibrancy that sets them apart from other stone types, such as sapphires or rubies. They make great centerpieces for necklaces and earrings due to their subtle yet stunning hue.

  • Light

    Light-colored diamonds are often used for accents because of their muted tones that do not overpower other gems in the design of a piece of jewelry. Despite having less color saturation than higher grades, such as fancy vivid or intense, light-colored diamonds still contain enough hue to set them apart from clear stones like white diamonds or topaz gems.

  • Very Light

    Very light-colored diamonds are similar to light-colored ones but with even less hue and color saturation than their counterparts in higher grades, such as fancy light or vivid stones, respectively—making them ideal accent pieces for any jewelry item you choose.

  • Faint

    Faint-colored diamonds do not possess much hue at all; however, they can still be used in certain pieces of jewelry where their lack of vibrancy allows other gems, such as ruby or sapphire stones, to shine without competition from nearby gemstones.

In terms of value, whilst colorless diamonds decrease in value as their color becomes stronger, whereas fancy natural-colored diamonds increase in value as the color becomes more vivid and pure. So the stronger the hue of natural fancy-colored diamonds correspondingly, the more valuable the diamond.


The Hope Diamond is perhaps the most famous of natural fancy-colored diamonds. It is deep blue in color with VS1 clarity and has a cushion antique brilliant cut with a faceted girdle and extra facets on the pavilion. This stunning diamond is of a deep blue color and is an impressive 45.52-carat stone. The Hope Diamond was originally extracted in the 17th century from the Kollur Mine in Guntur, India. It is widely acknowledged as one of the most sought-after diamonds, and its ownership can be traced back over four centuries.

Other famous natural fancy-colored diamonds include the Tiffany diamond, which was mined in South Africa in 1877 and is a canary yellow diamond of 128.54 carats. The most famous fancy-colored red diamond is the Moussaieff Red, mined in the 1990s in Brazil; its extracts were measured at 13.9 carats but were cut down to 5.11 carats. The Dresden Green is a natural apple green diamond believed to have been mined in India in 1722 and is an impressive 41-carat.

Fancy-colored diamonds can often be even more expensive than traditional colorless diamonds, especially if they are vivid in color. The rarer and more unique the color of a diamond is, the higher its value will be. Unfortunately, there's no such thing as a cheap vibrant fancy-colored diamond — these precious stones carry a large price tag because of their intense visuals and luxurious charm.

That being said, not all fancy-colored diamonds are more expensive than normal diamonds. At Rêve Diamonds, we offer our retail customers wholesale prices, meaning you can buy diamonds at a much lower price than other jewelers can offer.


Fancy-colored diamonds are nothing new, but with their resurgence in popularity, it's only natural to question the legitimacy of these mysterious gems. The good news is that, yes, fancy-colored diamonds are truly real. But here's the exciting part: no two fancy-colored diamonds will ever be exactly alike because each gem naturally produces its own unique deep color and texture due to trace elements found inside the particular diamond’s crystal lattice structure during its formation process. Whether for a stunning engagement ring or a special gift of global luxury, a genuine fancy-colored diamond is an exquisite treasure.


Fancy-colored diamonds are appealing as a luxury investment. Sometimes called "investment grade" diamonds, these gems come in a range of vibrant, intense colors from red to green and beyond. For investors looking for a unique and timeless asset to add to their portfolios, fancy-colored diamonds offer the opportunity for appreciation over time based on current demand and intensity of color.

Investing in fancy-colored diamonds can be complicated, so it's important to find knowledgeable experts who understand the grading principles and market trends before making a purchase. With help from the right professionals, fancy-colored diamonds can be an attractive option for those searching for a way to add value and luxury to their long-term investments.
