The clarity of a diamond refers to the natural inclusions, imperfections and flaws within or on the stone. Like snowflakes, no two diamonds are ever alike.

Learn About a Diamond's Clarity Here

Diamond clarity is graded under a 10X-power magnification by a trained-eye and is determined by the number of inclusions, their type and location.

There are two types of clarity grading:

ADX Tip: If considering a lower clarity diamond, choose one where the inclusion can be hidden by the jewelry setting.

ADX Tip: A lower quality in clarity affects the light flow therefore, the sparkle of a diamond.

Diamond clarity is based on a scale from Flawless (F) to I3 and the location of the flaws affecting the grading also. For example, a VVS1 diamond may have an inclusion or blemish close to the edge of the stone, whereas a VVS2 diamond's flaw may be located under the Table which is more noticeable.

ADX Tip: A lower clarity diamond may be considered for earrings or pendants where it will not be examined as frequently or as close-up.

Flawless (F)
Flawless diamonds show no inclusions or blemishes of any kind under 10X-power magnification.

Internally Flawless (IF)
Shows only insignificant blemishes and no inclusions when examined under 10X-power magnification.

Very Very Slightly Included (VVSI)
Contains miniscule inclusions that range from extremely difficult (VVS1) to very difficult (VVS2) to locate. It may show a miniscule pinpoint or two.

Very Slightly Included (VSI)
Contains minor inclusions that range from difficult (VS1) to somewhat easy (VS2) to locate. Typical inclusions are small crystal feathers or a distinct cloud.

Slightly Included (SI)
Contains noticeable inclusions that are easy (SI1) or very easy (SI2) to locate. Eye-visible inclusions are more often seen in an SI2 stone.

Included (I1, I2, I3)
Contains inclusions that are obvious face-up without magnification. These inclusions seriously affect the stone's durability and are so large or numerous that they affect transparency and brightness.

ADX Tip:
Rings are an important part of everyday life for most women and will be frequently admired and examined by both the owner and onlookers alike. As such, we recommend Very Slightly Included (VS) to Slightly Included (SI) diamonds for rings.
