How Are Fancy Color Diamonds Made?
The most magical thing about fancy colored diamonds is that it is a natural occurrence. The colors in diamonds come from tiny specs of impurities in the carbon lattice structure of the gemstone as it forms in the depths of the earth. The most common element found in diamonds is nitrogen, and depending on its concentration it can produce a yellow or brown tint in a diamond.
The very rare blue diamond has boron impurities in its composition and the purple ones are caused by a mix of crystal lattice distortion and highly concentrated hydrogen. The rarest fancy colored stone is the red diamond. It is so unique that there is not much information about its formation. However, scientists believe that unlike other fancy stones, red and pink diamonds are not caused by impurities but actually because of a natural alteration of its crystal lattice structure occurred in the diamond’s transportation to the surface of the earth.
How Are Fancy Diamonds Graded?
A diamond grading report by a reputable grading laboratory is the most important thing to consider when making a purchase. Grading fancy color diamonds is significantly different than grading colorless diamonds. Fancy diamonds are graded on a nine-point scale: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Dark, Fancy Intense, Fancy Deep, Fancy Vivid. The difference between one level of saturation and the other can be between 50-100%. Laboratories use a list of 27 shades that make the entire spectrum of fancy color diamonds.
