Diamond Grading Series_ CLARITY


The clarity of a diamond refers to the presence or absence of inclusions (internal flaws) and blemishes (external flaws) within the diamond. Clarity is another one of the "Four Cs" of diamond grading, along with color, cut, and carat weight.

Diamonds are graded on a scale of 6 categories ranging from Flawless (FL) to Included (I3). The grades are as follows:

  1. Flawless (FL) - No inclusions or blemishes visible under 10x magnification. The rarest and most expensive grade of a diamond.

  2. Internally Flawless (IF) - No inclusions visible under 10x magnification, but some blemishes may be present.

  3. Very, Very Slightly Included (VVS1 and VVS2) - Inclusions are difficult to see under 10x magnification and are usually only visible from the pavilion of the diamond.

  4. Very Slightly Included (VS1 and VS2) - Inclusions are visible under 10x magnification, but are minor and not easily visible to the naked eye.

  5. Slightly Included (SI1 and SI2) - Inclusions are visible under 10x magnification and may be visible to the naked eye, particularly in larger diamonds.

  6. Included (I1, I2, and I3) - Inclusions are visible to the naked eye and may affect the diamond's durability and brilliance.

It's important to note that the clarity grade of a diamond can affect its value, but it's not the only factor to consider. Diamonds with slightly lower clarity grades may still be beautiful and valuable if they have excellent cut and color.
