What is a Fancy Color Diamond?
A fancy color diamond is a diamond that has more color intensity (saturation) than the GIA Z master stone (comparative standard) stone regardless of the hue including yellow diamonds, or diamonds of any color, such as blue, green, pink, orange, etc.
So what exactly is a master stone? A master stone is a stone of known color. When color grading, a diamond grader will compare a diamond to a set of master stones in order to determine which color grade to assign a diamond. Diamonds on the standard color scale range from D-colorless to Z-light yellow. Once a diamond has more color intensity than Z, then it is considered to be fancy color and is extraordinarily rare. G.I.A. uses fancy yellow master stones to grade color in diamonds that possess yellow body color.
Origin of Yellow Diamonds
Fancy yellow diamonds, sometimes referred to as "canary diamonds", are found in various parts of the world. The most important source, however, is South Africa, where some of the most intense yellow diamonds have been discovered. Other notable regions include Angola, Central Africa, the Democratic Republic Of Congo, Sierra Leone, Australia, Canada, Brazil, Borneo, and Russia.
The Cause Of Color Of Fancy Yellow Diamond
The unique yellow color of these diamonds is attributed to the presence of nitrogen in their composition. Nitrogen molecules absorb blue light, which results in the stone appearing yellow.
The more nitrogen present, the more intense the yellow hue becomes, transforming it from a perceived liability into an asset. Some may have a gorgeous secondary hue, such as orange that produce extremely attractive diamonds.
The Special Nature of Fancy Yellow Diamonds
Fancy yellow diamonds are special due to their rarity and stunning hue. They are part of the group of natural fancy-colored diamonds, which constitute only one out of approximately 10,000 stones mined.
This makes them highly sought after by collectors and enthusiasts alike. Diamonds come in every color of the rainbow, with brown and yellow being the most abundant. Although fancy yellow is one of the most abundant, top-quality fancy intense yellow and fancy vivid yellow stones in large sizes are rare and some of the most beautiful diamonds on earth.
For this reason, those that are formed naturally will sell at higher prices than treated fancy colors or colorless diamonds.
Fancy Color Diamond Grading System
Gemologists use defined color grading scales to evaluate the value and differentiate between different hues of fancy yellow diamonds.
The Gemological Institute of America (GIA) grades fancy-colored diamonds based on three attributes: hue, tone, and saturation. The hue refers to the actual color of the diamond, the tone represents the relative lightness or darkness, and the saturation defines the color's strength or intensity.

The term "canary yellow diamond" although popular, is a subjective description and not easy to measure, therefore dealers and gem labs defer to the descriptions provided by the GIA, the authority when it comes to fancy color diamonds.
Natural vs Treated Fancy Yellow Diamonds
Natural fancy yellow diamonds achieve their color through geological processes over millions of years. Treated or enhanced yellow diamonds, on the other hand, are subjected to high temperatures and pressures in controlled conditions to alter their color artificially.
While these treatments can improve the diamond's color, they significantly reduce its value compared to a natural fancy yellow diamond, but nonetheless can produce a beautiful yellow color, at a lower price.
Lab-Created Fancy Yellow Diamonds
Lab-created fancy yellow diamonds do exist, in fact they were much easier to produce for commercial purposes than colorless diamonds.
These synthetic diamonds have the same physical and chemical properties as natural diamonds but are created in a laboratory setting over a much shorter time period. While they offer a more affordable alternative, they lack the rarity and inherent value of naturally occurring fancy yellow diamonds.
