What Is a Fancy Yellow Diamond?

The concept of Fancy yellow diamonds

Fancy yellow diamonds are a type of natural colored diamond with a prominent yellow hue. This type of diamond is also called a "Fancy Yellow Diamond" or "Canary Diamond" when the yellow color has a particularly intense saturation. The yellow color of Fancy diamonds is due to the presence of the element nitrogen in their crystal structure. Nitrogen absorbs blue light, causing the diamond to appear in different shades of yellow.
 

The concept of Fancy yellow diamonds

Similar to transparent diamonds, yellow diamonds are also evaluated based on the 4Cs standard to assess quality. However, instead of focusing on clarity and weight, yellow diamonds are more valued for their color and color intensity.

For colorless diamonds, commonly called white diamonds, GIA divides them into 5 color groups including: colorless, near colorless, faint yellow, very light yellow, and light yellow. As for yellow diamonds, GIA divides them into 6 groups as follows:

  • Fancy Light Yellow
  • Fancy Yellow
  • Fancy Intense Yellow
  • Fancy Vivid Yellow
  • Fancy Deep Yellow
  • Fancy Dark Yellow

Therefore, Fancy yellow diamond is considered a term used to describe the color of yellow diamonds. However, this term has not been officially recognized. In general, the deeper the yellow hue of a yellow diamond, the greater its value.

Structure of Yellow Diamonds

Transparent diamonds (colorless) are the type that contain carbon. This type of diamond is classified according to its color scale (D-Z color scale) from completely colorless to light yellow. The more yellow tint a diamond has, the duller it looks and the lower its value. However, when yellow becomes the dominant color, it is called a Fancy yellow diamond. This is a rare type of diamond on the market, so their value is extremely high.

Structure of Yellow Diamonds

Yellow diamonds contain a portion of nitrogen within their structure

Similar to white diamonds, yellow diamonds are formed from carbon elements but contain an additional portion of nitrogen within their structure. Therefore, they have a uniquely striking yellow color.

How Rare Are Yellow Diamonds?

The process of mining rough diamonds is very harsh and in some places is even associated with the issue of blood diamonds. Therefore, yellow diamonds are scarce in quantity. It is estimated that only 0.0001% of colored diamonds are found. For this reason, colored diamonds are extremely valuable and can reach tens of millions of dollars.

Yellow diamonds are also called Canary Diamonds, which translates to canary diamonds. This name is used to describe diamonds with a deep yellow hue and high clarity. When exposed to light, creating light reflection, these Canary diamonds sparkle like sunlight. They create a fresh and positive source of energy. Therefore, this is a type of diamond loved and sought after by connoisseurs.
