The most significant impact on its appearance is COLOR. With its many prismatic facets, a colorless diamond reflects light into a spectrum of hues, a characteristic often referred to as “fire”. The presence of noticeable color in a diamond may reduce its ability to reflect light. Also, diamonds with lower color grades will not show the same luminosity and fire as those with higher grades. The most valuable diamonds have little to no detectable color.
- For the purist, look for a Colorless grade of D-F for a diamond with no discernible color under magnification.
- For the best value, choose a Near-Colorless grade of G-J for a diamond with no discernible color by the naked eye.
- Consider platinum or white gold settings when buying higher color grade diamond; a gold setting may show through a colorless diamond.
Highest-quality color grade a diamond can receive. A D-color diamond is extremely rare and emits unrivaled brilliance.
Contains very minute traces of color. Also a rarity, an E-color rated diamond emits a high level of brilliance and sparkle.
Minute traces of color can only be detected by a trained gemologist. This is a high-quality color grade.
G,H (Near Colorless)
Contains noticeable color only when compared to higher color grades. Appearing colorless to the untrained eye, a G or H color diamond provides an excellent value.
I,J (Near Colorless)
Contains slightly detectable color. An I-color or J-color diamond is an excellent value, as it typically appears colorless to the untrained eye.
K,L,M (Faint Yellow)
Faint color is noticeable. Even with the presence of color, these grades of diamonds can emit fire and beauty.
