Fancy diamonds are natural diamonds that possess special colors, falling outside the usual range from colorless to light yellow (D-Z). Unlike white diamonds, Fancy diamonds have distinct hues such as pink, blue, deep yellow, or red, formed by atomic substitution or crystal structure transformations deep within the earth.

This article will delve into the technical definition, the formation mechanism of rare pigments, and the valuation hierarchy of colored diamonds in today's market.

What are Fancy Diamonds?

Fancy Color Diamonds are diamonds with natural colors that go beyond the limits of the standard GIA scale. Their value lies not in absolute clarity but in the intensity and saturation of their color.

Fancy Color Diamonds are diamonds with natural colors

The formation mechanisms of Fancy diamond colors include:

  • Trace element presence: For example, Nitrogen creates yellow, and Boron creates blue.
  • Structural deformation: Extreme pressure alters the crystal lattice structure, creating pink or red colors.
  • Natural radiation: Exposure to radioactive particles deep within the earth over millions of years creates green colors.

Colors of Fancy Diamonds

Fancy diamonds boast a diverse range of colors, from common tones to extremely rare shades. Their colors are grouped based on the trace chemical elements or crystal structure transformations during their natural formation.

Green Diamond

Green is the rarest color among fancy diamonds. This is because green diamonds are only formed through the process of uranium radioactive contamination.

Pink diamonds are highly favored by royalty and the elite. These diamonds are not only symbols of high fashion but also evoke feelings of joy and happiness in their owners. A prime example is the world-famous Pink Star diamond ring, which was once auctioned for over 80 million USD. Most pink diamonds are mined at the Argyle mine and are said to have extremely high purity, without inclusions like other colored diamonds.
