The Grading of

Diamond Color

A diamond's coloration is just how naturally white the stone appears. Most white diamonds in nature tastefully show a faint hint of yellow. When talking about a "colorless" diamond, it doesn't display any notable hues – these are typically quite rare. The industry regulates color grading by comparing each rock to a master set. Then assign it a letter anywhere from "D" (no hue) to "Z" (light yellow).

Diamond Color

Chart overview

Diamonds that fall into the "colorless" and "near-colorless" range are the only ones that Dórnor accepts. In other words, D color diamonds, E color diamonds, F color diamonds, G color diamonds, H color diamonds, and I color diamonds are the only ones Dórnor will accept for rings. Due to this, diamonds with a borderline color grade receive a more conservative rating.

DEF: Colorless

GHIJ: Near Colorless

KLM: Faint Yellow

NOPQR: Very Light Yellow

STUVWXYZ: Light Yellow

Does Diamond Color

Really Matter?

Color is the second most essential 4Cs because the color grade directly affects the stone's appearance. For example, diamonds with a poor color grade can appear slightly yellow instead of the desired brilliant white. Additionally, Dórnor will not accept stones exhibiting strong or excessive fluorescence, which, in natural lighting, can give diamonds a milky appearance.
