Our fascination with diamonds is firmly rooted in the rarity of their existence. Their scarcity is one of the most integral parts of their value. This is the principle reason why colored diamonds are coveted so highly by their owners. Only one in 10,000 diamonds qualify as a fancy color. The grading scale is as follows: Fancy Light, Fancy, Fancy Intense, Fancy Vivid .
The more vibrant the color, the more valuable the diamond is. Yellow and brown are the most common of the fancy colors while pink, blue, and green are the rarest and most prized. Even rarer is the red diamond, of which only a handful are known to exist in the world today.
What do I need to know when buying a fancy color diamond?
The traditional color scale (D‐Z) does not apply to fancy colors (see image above). Hue and vibrancy are the most important factors in valuing a color diamond. Inclusions (clarity) play a much less important role in pricing unless they significantly detract from the diamond’s face up appearance or the gem’s overall durability. It is also important to note that fancy shapes generally help intensify the natural color of the gemstone.
