Fancy Blue Diamonds |
GIA has made eight distinct color saturation grades for Blue diamonds:
Very Light - Light - Fancy Light - Fancy - Intense - Deep - Dark - Vivid
Additionally there are various color combinations that must be accounted for including; Gray-Blue and Green-Blue.
The more pure the color of the stone, generally the more desirable and rare the stone. However, a modifying color such as green, with high enough saturation, can increase the value of such a stone exponentially. |
