The reason fancy colored diamonds are fancies is most often the result of nitrogen and boron impurities. Occasionally the color of a diamond is the result of structural defects within the diamond crystal.
The presence of dispersed nitrogen within a diamond may cause the diamond to exhibit a yellow color. The presence of boron may cause the diamond to be blue in color, like the Hope diamond.
Pink, red, and purple colored diamonds are believed to result from pink graining (lamellae) or deformation of the diamond structure. That results in pink coloration in what would otherwise be a colorless diamond.
Fancy Green Colored Diamonds:
It is believed that most green diamonds are green because of natural irradiation or hydrogen impurities. Black diamonds are colored by the presence of an abundance of graphite inclusions.
Fancy colored diamonds are always cut to compliment the color's depth and not necessarily visual performance. Thus the concept of "ideal proportions" can not be assigned to diamonds of fancy colors and intensities.
Fancy colored diamonds are valued by carat weight, clarity, and the depth or intensity of color. In that case, the proportions are not a selection factor with fancy color diamonds.
How to Describe Fancy Colors by Intensity:
The intensity of hue and saturation describes fancy colored diamonds. Deeper intensities and concentrations of color make the diamond more valuable and rare.
How evenly distributed the color is throughout the diamond is also taken into account. Here are the terms commonly used to describe the intensity of color in fancies:
Types of Colored Diamonds:
At present, there are three types of fancy colored diamonds available in the open market:
- 1Natural, untreated fancy color diamonds.
- 2Natural, treated/irradiated colored diamonds.
- 3Lab-grown and/or Lab-created colored diamonds.
It is perfectly natural to decide that a "natural, untreated fancy colored diamond" is the only option worth considering. However, it is also important to keep in mind that fancy colors' rare nature can make them quite expensive.
Falling in love with a natural fancy blue-color diamond's depth and beauty can be an expensive endeavor given that prices start in the range of one-hundred thousand dollars per carat for visibly included qualities.
Believe me; it can be a real eye-opener for people who are just beginning to familiarize themselves with fancy color prices. Check out the price of this fancy pink, deep purple color diamond from Blue Nile.
Natural, treated, and lab-grown fancy colored diamonds provide consumers outside the Hollywood realm with access to "the look" for a more reasonable price.
However, those options also have their downsides because the color might fade over time, and there have been stability issues with lab-grown diamonds.
