When it comes to diamonds, the more rare the stone, the more valuable they are. As far as normal diamonds, the absence of diamond color makes a stone more desirable. However, fancy colored diamonds are the complete opposite. The diamonds that are most saturated in color are the rarest and most valuable.
Grading colored diamonds is not a simple matter. In fact, the process is more complicated and specialized than grading even regular diamonds. More so than any other stone, it is important to trust a top-notch laboratory for grading these stones. The GIA systems for grading fancy colored diamonds accommodates the fact that each color may have different levels of saturation.
Pink diamonds get their specific hue from a rare compression of the crystal’s internal structure, known as “plastic deformation.”
