Like Red Diamonds Pink diamonds remain a mystery as to the geological science to what causes the pink. Some scientists believe it is due to an atomic level lattice defect that selectively absorbs light, producing a pink hue, but it is still a mystery, and this is only a theory.

Diamonds have four main characteristics when looking for quality; Color, Cut, Clarity, and Carat Weight. However, unlike colorless diamonds, where the 4Cs are of the same importance, the color of Fancy Color Diamonds is the most significant characteristic of all.

Pure colored pink diamonds without any secondary hue are more valuable. However, due to its magnificent appearance, a purplish-pink diamond is also considered most preferred.

Pink colored diamonds come in intensity grade in the GIA grading scale; Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Deep and Fancy Dark intensity grades depending on the color combinations within the stone.
