color

Diamonds vary in color from colorless to slight tones of yellow. Colorless & near colorless diamonds are most brilliant, most rare and most valuable. The following scale shows the GIA loose diamond color rating systems. The GIA (Gemological Institute of America) has established an industry-accepted color grading system that rates diamonds with alphabetical letters. D (no color) is the most expensive "color" and N through Z (very light to light yellow), the least expensive. Beverly Diamonds offers no diamond below a color grade of J.

Diamond Color
D Absolutely colorless. The absolute highest color grade possible, rare.
E Colorless. Colorless, a rare diamond with only small traces of color that can only be seen by a professional gemologist.
F Colorless. Very Slight color shown, if any, by a professional gemologist, and off course it is still considered a "colorless diamond".
G-H Nearly-colorless. Color can only be visible when being compared to other diamonds of better color grades, but these grades offer a great value & are a choice of many consumers.
I-J Nearly-colorless. Color slightly noticeable. These grades are usually offered at a great value.
K-M Noticeable color. Diamond of this low color grade is not carried by Beverly Diamonds.
N-Z Noticeable color. Diamond of this low color grade is not carried by Beverly Diamonds.
Diamond fluorescence

The Gemological Institute of America (GIA) and many other labs provide on their certificates whether or not a diamond has fluorescence. Now, Diamond fluorescence is a form of illumination that is created when a diamond is exposed to Ultraviolet (UV) light. Fluorescence on a diamond is rated from None to Very Strong. A Fluorescence grade of strong or very strong can make a diamond appear "cloudy" or "Hazy".

To provide you with advice, For diamonds in the colorless range (D, E and F) diamonds, we recommend no fluorescence or faint. For diamonds in the near colorless range (G - J) diamonds, medium or strong blue should be considered a neutral or it can have a positive affect and can improve the diamonds appearance and it will also be a great value.
