When you buy diamonds, never forget to get the diamond grading report that accompanies your expensive diamond. If you are not a jeweler, the contents of the report is incomprehensible.
The report includes a color grading scale using the following letters of the alphabet and the corresponding descriptions:
- Letters D, E, and F – means colorless.
- Letters G, H, and I – means very little color.
- Letters J, K, and L – means slight yellow color.
- Letters P, Q, R, S, T, U, V, W, and X-means darker shade of yellow.
- Letter Z- means fancy color – other than white or yellow.
Among the color grading scale, the expensive type is grade D while the least expensive is graded as X but diamonds which get a Z rating are considered the rarest and most expensive diamonds in the world.
Other aspects included in the diamond grading report can be confusing. You should talk to a jeweler you trust, and have them explain everything on the diamond grading report to you.
