    Fancy Color Diamonds Buying Guide:

    The fancy color in diamonds 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 diamonds are believed to be the result of pink graining (lamellae) or deformation of the diamond structure which results in pink coloration in what would otherwise be a colorless diamond.

    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 depth of the color 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.

    How to Describe Fancy Color Diamonds by Intensity:

    Fancy color diamonds are described by the intensity of hue and saturation. 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 fancy colored diamonds:

    • Fancy Deep.
    • Fancy Vivid.
    • Fancy Intense.
    • Fancy Dark.
    • Fancy.
    • Fancy Light.
    • Light.
    • Very Light.
    • Faint.

    Types of Fancy Color Diamonds:

    At the present time, there are three types of fancy colored diamonds available in the open market:

    1. 1
      Natural, untreated fancy colored diamonds.
    2. 2
      Natural, treated/irradiated fancy colored diamonds.
    3. 3
      Lab-grown and/or Lab-created fancy colored diamonds.

    It is perfectly natural to decide that a "natural, untreated fancy colored diamond" is the only option worth consideration. However, it is also important to keep in mind that the rare nature of fancy color diamonds can make them quite expensive.

    Falling in love with the depth and beauty of a natural fancy blue colored diamond 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 diamond prices.

    Natural, treated, and lab-grown fancy colored diamonds provide consumers outside the realm of Hollywood 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.
