majority of diamonds appear white in color, however, there are subtle differences,
which Color Grading is intended to define. The Gemological Institute of America
(GIA) Grading Laboratories use a color scale that ranges from D, E, F "colorless"
to Z "strong yellow". The "colorless" diamond is more valuable than a diamond
with a "hint of color to faintly yellow", although the grades between colorless
and the "near colorless" G, H, I, and J can really only be truly appreciated
by making a side by side comparison between diamonds of near equal size and
Diamonds of color grade K and lower have enough yellow color to be visually apparent, yet can still be considered a choice by some as their cost is much less than higher color grade stones.
