Color

The color of diamonds may vary due to the existence of natural impurities. Totally colorless diamonds are invaluable. With the increasing presence of color, the diamond’s quality decreases. The diamond color grades range from D to Z. DiaPure only accepts the D to H color diamonds, and never uses the diamonds that exhibit grey or brown tone.

D color is totally colorless, the highest color grade, and extremely rare.
E - F color is almost colorless. The color distinctions between a D color diamond and an E or F color diamond are only visible to an expert gemologist.

G - H color is nearly colorless. Although there is slight color difference between G - H color diamonds and higher quality diamonds, the diamonds of this grade are highly collectible.

  • I - J Color

    I - J color diamonds look nearly colorless, have hints of slight yellow, and demand high price.

  • K - M Color

    Faint yellow color visible to the naked eye.

  • N - R Color

    Very light yellow color visible to the naked eye.

  • S - Z Color

    Light yellow color visible to the naked eye.

DiaPure’s diamond color grading standards are based on the degree of colorlessness. DiaPure only chooses the D - H color in the “colorless” and “near colorless” range. Each DiaPure diamond is as pure as water, and has its unique value.
