  1. Learn more about diamond shape


    The cut, or facets, of a diamond is created by artisans. Well-cut diamonds let the maximum amount of light in and reflect it back to the eye. The better the cut, the more sparkly the diamond. Cuts are graded as ideal, premium, very good, good, fair, or poor. Generally, you should seek an ideal to very good grade.

  2. Learn more about carat weight


    A diamond’s weight is measured in carats. Carat weight and diamond size aren’t the same because cutting a diamond to different proportions affects its weight. Remember, carat weight alone doesn’t determine a diamond’s value. Bigger does not necessarily mean better. Instead, consider all four C’s to determine value. The diagram shows the relative size of various diamond carat weights, cut to the same proportions.

  3. Learn more about color


    The less color a diamond has, the more valuable it is. Diamonds are graded on a scale from D (colorless) to Z (light yellow).

  4. Learn more about clarity


    All but the rarest diamonds have small flaws, air bubbles, scratches, or other minerals. The fewer the flaws, the more valuable and beautiful the stone. Diamonds graded VVS2 to IF are rare and expensive. Most couples opt for ratings between SI2 and VS1. Clarity is nearly impossible for a layperson to evaluate, so it’s important to get an EGL or GIA certificate verifying diamond quality. This chart shows the clarity grading scale that has been established by the world’s foremost authority on diamonds, the Gemological Institute of America.

  5. Learn more about certification


    Cut is nearly impossible for a layperson to evaluate, so it’s important to get a GIA or EGL certificate from your jeweler to verify the quality of any diamond before you purchase it. A vast number of diamonds sold at Adolf Jewelers include a report from well-known independent gemological labs, such as the world-famous Gemological Institute of America’s Gem Trade Laboratory and the European Gemological Laboratory.
