Diamond color is rated on a scale from D (colorless) to Z (obviously yellow or brownish). Unless you are a diamond expert you will probably not be able to tell the difference between diamonds which are color graded D-I unless you are comparing diamonds side by side. Diamonds with higher color grades are rare and often command a premium price. However, color is largely a matter of personal preference and while some seek a near colorless diamond, others prefer a trace of color.


Color Grade D

D is the highest color grade and is reserved for a truly colorless diamond. It is completely colorless to the naked eye and much sought after because it is so rare.

Color Grade E

E grade diamonds are almost perfectly colorless, with only microscopic traces of color which can only be identified by diamond experts.

Color Grade F

F grade diamonds are almost totally colorless, with only minute hints of color which can only be detected by experienced gemologists.

Color Grade G

G grade diamonds appear nearly colorless to non diamond experts. This grade offers excellent value for money.

Color Grade H

H grade diamonds have a very slight tinge of color which is only perceptible when evaluated next to a colorless diamond. They appear nearly colorless to non diamond professionals and offer an excellent investment.

Color Grade I

I grade diamonds have very slight color traces which are only evident when compared to a colorless diamond. To non diamond professionals they appear nearly colorless.
