4C's : Color

Diamond color has a significant impact on its value. The color scale ranges from D to Z, from colorless to light yellow, respectively. To ensure the highest quality diamonds for your selection Diamonds On Web carries diamonds in the color range from D-K only. We do NOT carry any diamonds in the L-Z color range, to ensure you are selecting diamonds of the highest quality.

The farther from colorless the grade of a diamond, the less rare and therefore less valuable it is. 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), especially when it is mounted in jewelry. Diamonds with a J-Z color grade usually have yellow shading that can be detected by the naked eye, however, a well cut stone with good proportions will still release the brilliance and fire of a lower colored diamond, dispersing light in such a way so as to create a beautiful stone.

Diamonds also come in a range of natural fancy tones, such as blue, pink, green, and red. Such diamonds have so much color that they are not graded on the normal scale D-Z. Believe it or not, these fancy diamonds are particularly rare, and like their colorless counterparts, can also come attached to a high price tag. Bear in mind that color does not have an exclusive impact on a diamond's value. The value of a stone is affected by a combination of qualities including shape, clarity, cut, and carat weight, as well as its color.

Fluorescence

A bluish glow that comes from a stone exposed to ultraviolet light. The effect of fluorescence depends on the combination of the color of the stone in question and the strength of the fluorescence. Faint fluorescence has very little effect on a stone of any color. Medium blue fluorescence and strong blue fluorescence can have a positive effect on stones of low color (J or worse). The fluorescence actually has the effect of making the stone look closer to near colorless. On stones of high color (D-G), strong or medium blue fluorescence can make the stone look milky instead of colorless or near colorless.

Diamonds On Web Best Value: Color

For the best value in diamond color, Diamonds On Web only carries diamonds in the color range of D-K. Diamonds with a higher color grade, appear whiter. The whiter the stone, more light is able to pass through it, making it sparkle and shine. Diamonds with a color grade of K and higher are near-colorless or colorless, and are recommend best value, since their color is undetectable to the untrained and unaided eye.
