Learn about the inclusions and blemishes that make a diamond unique

Diamonds are formed deep within the earth's crust. Extreme heat and pressure transform carbon into diamonds. However, not all molecules are fully transformed, resulting in the so-called inclusions, the internal “birthmarks” of a diamond. External flaws are called blemishes.

Diamonds without any blemishes or inclusions at all are practically non-existent and those with very little flaws exceedingly rare. The clarity of diamonds is examined under 10x magnification, and no diamond is absolutely perfect in this view. Those diamonds that come close are highly valuable due to their rarity.

The GIA Clarity Scale

The Clarity Scale applied by the GIA ranges from Flawless to Included and measures the absence of inclusions and blemishes.

FL

Flawless

Not even a skilled grader can identify inclusions or blemishes under 10x magnification

IF

Internally Flawless

The diamond has no visible inclusions and only a skilled grader can detect blemishes using 10x magnification

VVS1 and VVS2

Very, very slightly included

It is difficult for skilled graders to see inclusions under 10x magnification

VS1 and VS2

Very slightly included

Minor inclusions, that are difficult to easy to detect by a skilled grader

SI1 and SI2

Slightly included

The inclusions are definitely noticeable for a skilled grader under 10x magnification

I1, I2, I3

Included

The inclusions are obvious under 10x magnification and probably affect transparency and brilliance of the diamond
