The 4 Cs of Fancy Color Diamonds: It’s All About the Color

In general, diamonds are defined and appraised based upon four elements, also called the 4 Cs. The 4Cs stand for the Clarity, Color, Cut, and Carat, and all four of these aspects are crucial for understanding and determining the true value of a diamond.

 

However, this way of evaluating diamonds is geared specifically toward colorless diamonds, where all 4 C’s are equally important, and less so for color diamonds for the simple reason that the color factor of color diamonds is the most important ‘C’.

 

Let us take a look at Fancy Color Diamonds, their color, and why it has such power over the remaining 3 Cs.

 

Defining Color Diamonds

 

The term Fancy Color Diamonds refers to natural diamonds which exhibit any sort of color. A diamond is actually a geographical element that is made of carbon in a crystal lattice structure that is formed millions of miles under the Earth’s surface. All diamonds are rare, but those gifted with unusual color tones are even rarer, and for the most part, far more valuable.

 

The 12 colors of diamonds: Yellow, Pink, Blue, Gree, Prange, Brown, Violet, Gra, Purple, Red, Black and White

 

Every color was created as a result of a specific element that got incorporated into the structure of the diamond during its formation, or alternatively, as a result of the rough conditions that the diamond endured over time. For example, a yellow diamond receives its color from the presence of nitrogen, and a blue diamond owes its sensational coloring to the element boron. Though it is still disputed, it is widely believed that pink diamonds receive their incredible hue from incredible pressure diamond’s crystal lattice.

Yellow in diamonds may be familiar to some because of the ‘C’ of color in colorless diamonds. However, though those diamonds also qualify as color diamonds, on the very bottom of the color diamond scale, they are not quite the stones to have in mind when picturing a fancy color diamond.

Diamonds with unique and rare colors such as pink, green, blue, yellow, red, orange, black, brown, gray, violet, white and purple hues, in various shades with assorted overtones, are what characterize this prestigious diamond category. Color is so important in color diamonds that there are two color-sub-categories: Color Intensity and Hue. This refers to the level in which the color is seen, and the exact color of the stone, as it can be one pure color or a combination of two or more colors. Generally, the rule of thumb is that the more pure and intense a color is (without secondary hues), the more valuable it will be.

 

Color Intensity

 

As with most of the 4 Cs, the color intensity of a fancy color diamond is assessed according to a scale. Just like colorless diamonds are graded according to their lack of color from least to most on a scale from D-Z, color diamonds are graded according to the strength of their color, from least to most, on a scale from Faint to Vivid. The color intensity grading scale works as follows: The lowest grade, (which is equivalent to an S-Z color grade on the colorless color grading scale in the case of Yellows), is Faint. Next is Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, and Fancy Deep.

These eight color intensity levels are not available for all diamond colors because the color in different diamonds is caused by different factors and therefore it presents itself differently in different colors. The best example is in black red, and white diamonds, which all can only be graded with the Fancy color intensity level. (nor can black or white diamonds have overtones, although red can have an overtone of purple , orange or brown). The higher the color intensity level, the more valuable the diamond although desirability changes depending on personal taste.

Primary and Secondary Hues

 

A fancy color diamond can be in one pure color, or have up to 3 modifying colors to the main color.. For instance, a pure Fancy Yellow diamond is one without any secondary hues such as green and orange. A Fancy Yellow Diamond with one secondary color could be an Orange Yellow Diamond whereas one with two secondary colors could be a Brownish Orangy Yellow Diamond. The secondary color is designated based on the concentration of its presence, so a Fancy Brown Yellow diamond has more brown than a Fancy Brownish Yellow diamond.

Additional Names for Color Diamonds

 

For the most part, Fancy Color Diamonds are referred to by their colors, but there are several color categories that have additional names. For examples, brown diamonds can also be known as Chocolate Diamonds, Cognac Diamonds, or Champagne diamonds. Yellow diamonds are also commonly called Canary Diamonds, and a specific kind of yellow diamonds are called Zimmis. While these terms are largely due to marketing tactics, they can sometimes refer to specific types of diamonds in that designated color category. A Canary diamond, for instance, is not just a yellow diamond, but one that is Fancy Intense Yellow or Fancy Vivid Yellows. A Zimmi diamond is a yellow diamond from Sierra Leone.

 

Cut, clarity, and carat size also play important roles in regards to the worth of a colorl diamond although they most definitely take a back seat. When it comes to Fancy Color Diamonds, it’s all about the color.
