The 4 C's of Diamonds - Clarity

CLARITY

Natural diamonds are created when carbon is exposed to extreme heat and pressure deep in the Earth. During this process, various internal characteristics called 'inclusions' and external characteristics occur.

Every diamond is unique and can be recognised by the unique fingerprints of these little marks.

 

Grading a diamond's clarity involves determining the number, size, type, and position of these inclusions and how they affect the stone's appearance and durability.

 

Remember that no diamond is perfectly pure. But the closer it comes to purity, the better its clarity is. Clarity grading ranges from internally flawless stones (FI/IF) to those that have tiny inclusions which can just be seen by the naked eye.

EC One uses diamonds of S1 clarity and above.

 how diamond clarity is graded

 

Flawless (FL) No inclusions and no blemishes visible under magnification.


Internally Flawless (IF) No inclusions visibleunder magnification. 


Very, Very Slightly Included(VVS1 and VVS2) Inclusions so slight they are difficult for a skilled grader to see under magnification.


Very Slightly Included (VS1 and VS2) Inclusions are observed with effort under magnification.


Slightly Included (SI1 and SI2) Inclusions are noticeable under magnification.


Included (I1, I2, and I3) Inclusions are obvious under magnification which may affect transparency and brilliance and even durability.
