Color, while applied to white diamonds, is often misunderstood by people outside the diamond industry.

Most people imagine that all white diamonds are colorless. In fact, truly colorless diamonds are quite rare. The diamonds used mostly in jewelry are nearly colorless with pale yellow or brown tints. These diamonds drop into the usual color range. In the normal colour range, the nearer to colorless, the more attractive and valuable the diamond.

In the 1950’s, the D-Z color grading scale introduced by GIA that is stills the industry standard.

GIA Colour Grade Scale
D – F: Colorless
G – J: Near Colorless
K – M: Faint Yellow
N – R: Very Light Yellow
S – Z: Light Yellow

How is color calculated?

Color in white diamonds is normally calculated by comparing the diamond with the set of ‘master stones’. The maximum ‘master stone’ is E-color. Any diamond enhanced than the E-color master is rate d D-color.

Each color grade is really a skinny range of colors. There is no one accurate color for any GIA color grade scale. So, an F-color diamond can be a physically powerful, standard or weak F-color. Though, as long as the diamond is better than the G-color master, it receives an F-color grade.

Fluorescence

Fluorescence is an exclusive effect that causes some diamonds to create a glow (typically blue or yellow) when showing to a strong ultraviolet light. Some favor a diamond with some ‘blue fluorescence’ because it may create the diamond in the ‘near colorless’ or ‘faint yellow’ ranges look rather whiter.

In the ‘colorless’ range, fluorescence has no result on color, although it can reason the diamond to have a little milky appearance.

Why diamond’s color grade is important?

The luminous, fiery, sparkles of light that radiate from an elevated quality white diamond are matchless by some other gem. The diamond acts similar to a prism, dividing light into spectral colors, which are then reflected as color flashes, known as fire. Any usual color in the diamond filters the light, falling its fire and brilliance.

The fewer colors in the diamond, the more bright the fire, and the better the diamond’s color grade. The better the color grade, the more attractive and valuable the diamond.
