Clarity is usually the easiest of The 4 Cs to understand... it's a grade of how clear the diamond appears to be.
The clarity of a diamond is the measurement of the number, size, and position of tiny imperfections and their impact on the diamond's appearance. Natural diamonds are the result of carbon that has been exposed to excessive heat and pressure deep in the earth. During this process, internal characteristics called inclusions and external characteristics called blemishes occur. There is no diamond that is perfectly pure, however, the closer it comes, the higher its value.
A diamond's clarity is graded under a 10x magnification and given a grade that falls under the following:
- Flawless (FL)
- This grade is given to diamonds with no inclusions and no blemishes visible.
- Internally Flawless (IF)
- No inclusions are visible.
- Very, Very Slightly Included (VVS1 and VVS2)
- Diamonds that fall into this category have inclusions that are so slight they are difficult for a skilled grader to see.
- Very Slightly Included (VS1 and VS2)
- Minor inclusions, but are observed by the grader.
- Slightly Included (SI1 and SI2)
- Inclusions are noticeable under the designated 10x magnification.
- Included (I1, I2, and I3)
- Inclusions are obvious and they may affect transparency and brilliance.
