C O L O R
The most valuable color is no color or very intense color (i.e.,
fancy yellow). A totally colorless diamond allows white light to
pass effortlessly through it and be dispersed as lovely rainbows of
color. The grading of color is expressed with a letter, such as D,
representing the best and most transparent.
