Fancy diamond colors

Gem diamonds in GIA’s D-to-Z range usually decrease in value as the color becomes more obvious. Just the opposite happens with fancy color diamonds: Their value generally increases with the strength and purity of the color. Large, vivid fancy color diamonds are extremely rare and very valuable. However, many fancy diamond colors are muted rather than pure and strong.

Diamond investment is low risk with high yield returns.

With only one out of 10.000 diamonds being a natural colored diamond, these gem stones are rare. Pink diamonds have shown a continual growth in value year over year. The market has seen an average price per carat of $1.5 to $3 million per carat. Investors and collectors are taking notice of these increasing values, and as supply decreases with the upcoming closure of the Argyle Diamond Mine , the demand is expected to continue to drive up the prices. Investing starting from DKK 100.000.

The Gemological Institute of America (GIA) developed the 4 Cs – Color, Clarity, Cut and Carat Weight. They used this as a benchmark to how a diamond is valued. Previous to this internationally recognized grading system, there were no such standards in place. Hence a value of a diamond was very subjective.

  • Color

    The GIA developed the D-to-Z color grading scale 50 years ago to show the range of color that a diamond has. ``D`` represents the colorless spectrum; while the opposite side of the spectrum is ``Z`` which represents the light color end.

  • Cut

    Natural Fancy Colored Diamonds are unique with graining to show its colors. If your intent is to turn your loose diamond investment into jewelry, then the right type of cut (size and shape) will make all the difference in the value of your Fancy Colored Diamond.

  • Clarity

    Fancy Color Diamonds will naturally have graining to them. They generally will not be as clear as a color-less diamond. However, a low clarity FCD can still be highly sought after. As long as these FCDs have an exquisite face-up color, they will be in high demand!

  • Carat

    The carat is the weight of the diamond. The bigger the diamond the rarer it is. However, when it comes to investing in loose natural colored diamonds, it’s better to diversify your portfolio. Hold more variety to ensure that you maximize your short and medium term returns.
