Diamond Grading Reports Crash Course


As I mentioned in my previous post, having a certificate or a diamond grading report is very important, and for your own good, you want to get one. Unfortunately, you probably won’t understand a word of what is on that diamond grading report, unless you are in fact, 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 which by all means, other than white or yellow. On the color grading scale, D would be the most valuable, and X is the least valuable one. However a diamond that gets a Z rating would be the rarest and most expensive diamond in the world.

There are many aspects to a grading report. Figuring it all out can be very confusing. The best way is to talk to a jeweler you trust, and have them explain everything on the diamond grading report to you.

Also remember a diamond grading report is only as good as the laboratory it comes from. A cert may not be reliable if issued by the retailer, or an unqualified organisation working with the retailer. If you are unsure do some checking.

That is very true. One of the most reliable laboratory is the Gemological Institute of America (GIA) which we recommend to all.
