Diamond Color

What is Diamond Color ?

Color is considered the second most important diamond characteristic after "cut". The human eye detects a diamond's brilliance first, then its color second.

Colorless diamonds are the most desirable since they allow the most refraction of light (sparkle). Color is a result of the composition of the diamond, and it never changes over time.

To grade 'whiteness' or colorlessness, most jewelers refer to GIA's professional color scale that begins with the highest rating of D for colorless, and travels down the alphabet to grade stones with traces of very faint or light yellowish or brownish color. The color scale continues all the way to Z.

How diamond color is graded?

Diamonds graded D through F are naturally the most valuable and desirable because of their rarity. Such diamonds are a treat for the eyes of anyone. But you can still obtain very attractive diamonds that are graded slightly less than colorless. Additionally, diamonds graded G through I show virtually no color that is visible to the untrained eye.

  • D - F: Colorless
    This is the highest color grade that money can buy because these are absolutely colorless diamonds and extremely rare.
  • G - J: Near Colorless
    The very slight warmth and tone is difficult to detect unless compared side-by-side with diamonds of better grades. An excellent value, this color grade pairs well with yellow gold.
  • K - Z: Faint yellow to Light yellow
    The color grade from K to Z has no noticeable color.

Colored Diamonds

Colored diamonds are a spectacular alternative that is gaining in popularity (especially as we see more celebrities showing off their colorful engagement rings). Colored diamonds are graded in order of increasing intensity: starting from Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Dark and finally, Fancy Deep.

Diamond Flourescence

Fluorescence is an effect that is seen in some gem-quality diamonds when they are exposed to long-wave ultraviolet light (such as the lighting frequently seen in dance clubs). Under most lighting conditions, this fluorescence is not detectable to the eye.
