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 arethe 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.

All About the Clarity of Diamonds

Clarity is an important aspect of a diamond, and it is important to know how to grade the clarity of a diamond before you buy one. It is actually quite easy to learn how to grade the clarity of a diamond. There are basically two things that you must understand: Diamonds with visual inclusions and blemishes, and those that are ‘eye clean’ meaning that there are no inclusions or blemishes that can be seen with the naked eye. From there, the clarity of a diamond is further broken down into subcategories.

Many people mistakenly think that diamond clarity refers to how clear it is. This isn’t so. Clarity actually refers to the internal and external imperfections of the diamond. The best diamonds, of course get a grade of FL or IF – Flawless or Internally Flawless – meaning that it is perfect. A grade of I-1, I-2 or I-3 means that the diamond is imperfect, with a grade of I-3 being the worst.

Other grades are VVS1 and VVS2, which means that the diamond is very, very slightly imperfect; VS1 and VS2, meaning the diamond is very slightly imperfect; SI-1 and SI-2, which means that the diamond is slightly imperfect.
