A diamond’s color is graded using an alphabetic scale running from D to Z. The Diamond Color scale starts at D because it is believed that diamonds of A, B and C quality may still be found. The rarest and most valuable diamonds are those in the D-F range that are colorless, followed by G-H that are near colorless and then I-J that are slightly yellow tinted. It can be difficult to tell the difference between two color shades using the naked eye- only an experienced gemologist can determine the grade by comparing it to the color of control stones, which are preselected gems of a specific color. This is particularly true after the diamond has been set within the ring itself (once a diamond is set the metal can affect what we perceive is its color). It is also important to note that a poor diamond color can affect the brightness and brilliance of a diamond.
The diamond color scale below illustrates the color of a diamond and the corresponding code.

The following grading table gives the official grade, color and accurate comments of the various diamond color grades.
|D||Absolutely colorless||Colorless diamond. A high quality diamond.|

|F||Near colorless||Color is noticeable when compared to other diamonds.|
|G / H / I||Noticeable color||Color is detectable using naked eye.|
|J / K||Noticeable color||Color is detectable using naked eye.|

McQueen Jewelry Buying Tip:
For the best value in what would appear to the naked eye as a colorless diamond, look for E-F colored diamonds. Because color is easier to detect in larger diamonds, opt for E-F in diamonds over 1 carat, and G-H for those under 1 carat. Once set in a ring, these diamonds will look just like higher color grade diamonds. Instead of investing in higher color, invest in higher clarity, one of the most important factors in a diamond's brilliance. If you are concerned primarily about carat weight, and are on a tight budget, consider a yellow gold setting and a round diamond in the G-H color range; the yellow gold setting will distract the color from the diamond.
