Diamond color has a significant impact on its value. The color scale ranges from D to Z, from colorless to light yellow, respectively. Because a colorless diamond, like a clear window, allows more light to pass through it than a colored diamond, colorless diamonds emit more sparkle and fire.
|
| D:Absolutely colorless. The highest color grade, which is extremely rare.
E:Colorless. Minimal traces of color that can only be detected by an expert gemologist. Also a very rare diamond.
F:Colorless. Slight color, which can only be detected by an expert gemologist, but still, considered a “colorless” grade. A high quality diamond.
G-H:Near colorless. Color noticeable when compared to diamonds of better grades, but these grades offer excellent value.
I-K:Near colorless. Color slightly detectable. An excellent value.
L-M: Not carried at Diamonds on Fifth.
N-Z: Not carried at Diamonds on Fifth.

| At Diamonds on Fifth we sell only the finest diamonds with color graded D-K. When buying a diamond, take into consideration that it is often very difficult to detect the difference between a colorless diamond (D-F) and a near colorless diamond (G-H). Diamonds graded better than K are colorless or near colorless and their color is typically undetectable to the unaided eye.
What is Fluorescence?
Fluorescence is a bluish glow that comes from a stone exposed to ultraviolet light. Under most lighting conditions, this fluorescence is not detectable to the eye. While most gemologists prefer diamonds without this effect, some people enjoy it. Medium fluorescence and strong fluorescence can have a positive effect on stones of low color (K and worse). On stones of higher color (D-G) strong or medium fluorescence can make a diamond appear cloudy and hazy, which undervalues them on the market. Diamonds with a strong or very strong fluorescence are priced slightly lower than other diamonds.

Diamonds on Fifth Recommendations
While colorless stones are rarer and cost more, near colorless stones will look very much the same to the eye once set in jewelry. Choosing a G-K color instead of one in the higher DEF range will enable you to get a larger diamond for the money, without a substantial compromise in performance or beauty. If the diamond is to be set in white gold or platinum, Diamonds on Fifth recommends you aim a little higher on the scale than you would if setting it in yellow gold. Yellow gold disguises body color whereas white metal reveals it.
Fluorescence can add eye appeal to near colorless diamonds and therefore be a benefit. Diamonds on Fifth does not recommend fluorescence to a colorless stone as it may reduce its value.
