CLARITY

Diamond clarity is broken down into different categories according to the number of inclusions in the diamond. Inclusions are defects in the diamond itself, whether it be a crack, carbon spot, feathering of the crystal, or a surface blemish. The categories start with F-IF (flawless to internally flawless), VVS1-2 (very, very slight inclusions), VS1-2 (very slight inclusions), SI1-2 (slight inclusions), and I1-3 (imperfect).

There are different grades among each category described in the clarity chart. A jeweler’s 10X magnified loupe is the easiest way to view a diamond. If you can see inclusions at first glance with a loupe, you have an SI stone in your hands. If you really have to struggle to find an inclusion, chances are you are looking at a VS or better stone.

While VS quality diamonds tend to hold a higher value and are considered investment grade, we still see plenty of SI diamonds that would make an owner proud to display. In fact, SI diamonds are more common in jewelry than any other grade. We don’t recommend I clarity diamonds as these have inclusions that by definition are visible to the unaided eye.

Be careful of clarity enhanced diamonds. This is a process where a filler is used to give a diamond better clarity by hiding inclusions and cracks. It takes away from the value, but gives you a cleaner stone. Another process used to hide inclusions is laser enhancement. This turns a dark carbon spot to a lighter shade where it’s not noticeable. While GIA will certify a lasered diamond, it still diminishes the value. I don’t recommend either one of these and a jeweler is supposed to disclose this information. If the information is not volunteered, be sure to ask whether or not the diamond you are viewing is clarity enhanced.
