Fancy Colored Diamonds: The Complete Guide

Basic Information About Fancy Diamonds:-

Natural colored diamonds are very exclusive and rare, equally rarer than colored diamonds. A true natural colored diamond has been gifted to us by nature and can be found in a variety of colors from pink through yellow to brown and red. Color diamonds can only be found in very few regions, sometimes only in a few mines.

Only one in 10,000 diamonds is naturally colored and is called a colored diamond. When buying colored diamonds, the criteria are different than for colorless diamonds. At Gemistone Jewelers will receive useful information that will help you to find the right colored diamond for you. 

Colored Diamonds – In general, diamonds are considers particular valuable when they are pure white. The fancy diamonds are an exception, however. This term refers to all those diamonds that fall outside the usual color scale from D (very fine white +) to Z (yellow).

What does fancy mean as a word? 

The term fancy is derives from English and means “fancy, extravagant”, i.e. diamonds that have a strong full color. This includes all color varieties such as brown, yellow, pink, purple up to the rarest colors red, orange, green, and blue.

According to the world-leading Gemological Institute of America (GIA), experts estimate that only 1 carat in 10,000 carats of cut stones will be fancy colored. The probability of an intense coloring is many times lower.

What is a Colored Diamond?

Colored Diamonds are absolute impulses of nature. In contrast to the commonly known colorless diamonds with their various minimal color gradations within the color scale. Colored diamonds are stones whose color is caused by specific light absorption as a result of structural defects in the atomic lattice. 

What is a Colored Diamond

The coloring is not based on an actual coloring by foreign atoms, but a different optical-physical light absorption within the light spectrum of visible light. Certain positions (certain color centers) of the diamond atomic lattice are not atomically occupied or are occupied by foreign atoms. 

For example, yellow diamonds get their color from the nitrogen atoms embedded in the atomic lattice absorb the wavelength ranges of the blue light component. This makes the diamond seem yellow in its complementary color.

The Most Important Criteria when buying a Colored Diamond:-


The color intensity, namely the color depth or richness of color, is the most important parameter when purchasing a fancy colored diamond. The more intense the color, the rarer and more useful the diamond will be. Diamonds with lighter color intensities such as;

  • Faint, 
  • Very light, 
  • Bright, fancy light, and 
  • Fancy

Are more abundant than diamonds with richer color intensities such as; fancy intense, fancy vivid, and fancy deep and are accordingly worthless.

All fancy colored diamonds from Gemistone Jewelers Diamonds are 100% natural and untreated, which is also recorded in the diamond certificate ((on request). 

This fact is very important because fancy diamonds can also be created or modified in the laboratory through certain treatment processes with heat, pressure, or radiation. Unlike natural stones, however, these artificially “enhanced” diamonds are worth no more than the original diamond from which they were created. 

Other Quality Criteria of the Four C (4C’s Of Diamonds):-

Four C - 4Cs of Diamonds

The 4C criteria that determine the quality of diamonds(Color, Cut, Clarity, and Carat) are also applied to Fancy Diamonds but weighted differently. As already mentioned, the hue and the color intensity (color) are the most important characteristics for determining the value of a colored diamond.


The reason for the coloring in colored diamonds is different depending on the color. This is how yellow diamonds get their color thanks to the presence of nitrogen. Blue diamonds, on the other hand, include boron, which causes a blue color. 

The cause of the remarkable color found in pink and red diamonds is still unknown, but speculation has it that it is due to the variations resulting from deformations in the crystal structure. The rarer the color and the more prominent it is, the higher the value. Yellow and brown diamonds are the most common, while red, blue, and green diamonds are among the rarest of all fancy colors.


Next to the color grade, the carat weight has the biggest impact on the price of fancy colored diamonds. One carat is equal to 0.2 grams. The word “carat” comes from the “carob” source of the carob tree, the original unit of measure used by diamond traders. 

A peculiarity of these seeds is that they have a very uniform weight, so before the invention of today’s precision scales they were well suited as weighing weights.

As a diamond’s carat increases, diamond prices increase exponentially as the rarity increases. Less than one in a million unearthed rough diamonds are large enough to make a 1ct cut diamond. Diamond prices for fancy colored diamonds increase exponentially with carat weight.


The cut is also not considered a critical factor in evaluating a natural color diamond, since the diamond is typically fashioned to enhance the color as much as possible while having the maximum amount of weight from the rough crystal. 

This practice lends itself to brilliant cut types, as fought to step-faceted, with deeper cut proportions and thicker girdles on finished diamonds. The most ordinary shapes found in large fancy colored diamonds are radiant cuts and cushion cuts.

Clarity or Purity:

Because diamonds are formed deep within the earth, under extreme heat and pressure, unique birthmarks are often evident, whether internal (inclusions) or external (blemishes). The purity determination goes from LC (flawless) or IF (internally flawless) to I3 (including inclusions). The higher the purity determination on the spectrum, the more valuable and special, and the higher the price.

Because of the nature of fancy colored diamonds, clarity is less important than its colorless counterparts. This is correct as the inclusions are more likely to be disguised by the diamond color and there are very few colored diamonds that are completely flawless.

Types of Colored Diamonds

Diamonds can also be colored. The different shades of color are caused by impurities in the carbon. Only one in 100,000 diamonds is typically a fancy diamond because while many diamonds are colored, few are attractive and regular. The color of a diamond must be distinguished from the so-called fire, which merely describes how a diamond reflects rainbow colors and makes them sparkle. Fancy Diamonds are distinguished in different types of colors:

Blue Diamonds: “The Hope Diamond”

Blue Diamonds - The Hope Diamond 

The blue color of the stones is caused by the boron in the diamonds. In addition, it is noticeable with all blue diamonds that no nitrogenous impurities can be found in them. 

One of the most famous fancy blue stones is “The Hope Diamond”. The stone was discovered in the 17th century and weighed 112 carats in its raw state. However, it was ground down to 45 carats. The diamond, valued at around $200 million, can still be seen today at the National Museum of Natural History in Washington DC.

And indeed, several owners of the stone took their own lives. 

In addition to two other owners of the “Black Orlov”, the eponymous Russian princess Nadia Vygin-Orlov also fell to her death. The stone was then broken into 108 pieces and made into a necklace in the 1940s. The reason for the black coloring is less legendary: Graphite inclusions color the diamonds black.

In “fancy red” a price of around 1 – 1.5 million per carat would be expected if the stone were to be preserved. In the case of red and pink diamonds, this is partly because the Australian “Argyle” mine was one of the most famous sites for finding these colored diamonds: as it is now almost exhaust, the diamonds still on the market fetch very high prices.
