Ever wonder how diamonds get evaluated for color?
Learn about one of the 4Cs of Diamond Quality, Color Grading, created by GIA a universal standard measure for assessing diamond value.
Colorlessness
GIA’s diamond D-to-Z color-grading system assesses the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions against master stones of established color value.
The scale begins with the letter D, representing colorless, and continues, with increasing presence of color, to the letter Z.
