Color

Acting as a prism, a diamond can divide light into a spectrum of colors and reflect this light as colorful flashes called Fire. Just as when looking through colored glass, color in a diamond will act as a filter, and will diminish the spectrum of color emitted, The less color in a diamond, the more colorful the Fire, and the better the color grade.

Diamond Color

At Incendia Diamonds you will find only the finest diamonds with color graded D – J. Diamonds graded J or better are colorless or near-colorless – their color is typically undetectable to the unaided eye.

The color in diamonds graded K-Z detracts from the beauty of a diamond. It’s especially noticeable set in platinum or white gold.

Diamond Color

• D –  Absolutely colorless. The highest color grade, which is extremely rare.
• E –  Colorless. Only minute traces of color can be detected by an expert gemologist. A rare diamond.
• F –  Colorless. Slight color 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-J  – Near-colorless. Color slightly detectable. An excellent value.
• K-M  – Noticeable color.
• N-Z  – Noticeable color.

Fluorescence

Some people seek diamonds that produce this unique effect, while others avoid it. The visible effects of fluorescence; grades of faint, inert, negligible, and medium, can only be detected by a trained gemologist with specific UV light. A flourescence grade of strong or very strong can make a diamond with a near-colorless grade look even whiter. In some very rare instances a diamond with very strong fluorescence can give the diamond a slight hazy or oily appearance. Diamonds with a strong or very strong fluorescense can be a better value for the end customer because the market prices them slightly lower than diamonds with faint or negligible fluorescence.

What Color Grade is Best?

For the purist, look for a colorless diamond with a grade of D-F and a fluorescence rating of none, inert, faint, inert, or negligible.

For an excellent value in a diamond with no noticeable color to the unaided eye, look for a near-colorless grade of G-I, and a fluorescence grade of medium or strong blue.

Or, if you’d rather not compromise on color but would like to stay on budget, choose a diamond with a good cut, SI1-SI2 clarity, and consider going with a strong fluorescence. It will still be beautiful to the unaided eye and you may prefer the unique effect of strong fluorescence.
