Diamond Grading Reports

You’ve been told that having a certificate or

a diamond grading report is important, and

as a responsible consumer, you get one –

unfortunately, you probably won’t understand

a word of what is on that diamond grading

report, unless you are a jeweler.



On the color grading scale, D, E, and F

mean that the diamond has no color. G, H,

and I means that it has very little color. J, K,

and L means that the diamond has a slight

yellow color. P, Q, R, S, T, U, V, W, and X

means that the diamond is a darker shade

of yellow. Z means that the diamond has a

fancy color – other than white or yellow.

On the color grading scale, D is the most

valuable, and X is the least valuable –

however diamonds that get a Z rating are

the rarest and most expensive diamonds

in the world.



There are many aspects to a grading report.

Figuring it all out can be very confusing. You

should talk to a jeweler you trust, and have

them explain everything on the diamond

grading report to you.
