The next of the 4Cs is clarity.

A diamond’s clarity plays a very important role in its overall beauty and its value. Since diamonds are the result of carbon exposed to tremendous pressure and heat deep in the earth, the natural process results in a variety of internal and external characteristics. The characteristics coming from a diamond’s crystal structure and formation are called inclusions (internal) and blemishes (external).

Some may refer to inclusions and blemishes as “flaws,” but gemologists refer to them as a powerful grading tool. Since no two diamonds are the same, the unique combination of inclusions and blemishes help determine each diamond’s identity and separate natural diamonds from synthetics. The amount of inclusions and blemishes a diamond holds determines the clarity grade.

The GIA clarity grading scale includes 11 grades ranging from Flawless (FL) to Included (I3):

Flawless (FL) – No inclusions or blemishes are visible to a skilled grader.

Internally Flawless (IF) – No inclusions and only blemishes are visible to a skilled grader.

Very, Very Slightly Included (VVS1 and VVS2) – Inclusions are difficult for a skilled grader to see.

Very Slightly Included (VS1 and VS2) – Inclusions are clearly visible but can be characterized as minor.

Slightly Included (SI1 and SI2) – Inclusions are noticeable to a skilled grader.

Included (I1-I3) – Inclusions are obvious to the naked eye and may affect transparency and brilliance.

*All diamonds are viewed through a 10x magnification lens by diamond graders.
