The clarity of a diamond talks about the internal and external characteristic of a diamond, sometime referred to as impurities in the stone. This ranges from FL (flawless) to I2 or even I3 (visible to the eye)
This is graded using a 10X magnification, which allows to grader to inspect the internals of the stone.

  • IF - FL flawless/Internally Flawless= No inclusions visible, by an expert at 10X magnification
  • VVS1-VVS2= Very, Very slight inclusions very difficult for an expert to find under 10X 
  • VS1-VS2= Very slight inclusions difficult for an expert to find under 10X
  • SI1-SI2= Noticeable, relatively easy to find under 10X. Not visible w/o magnification in a face-up direction. 
  • I1-I3= Obvious under 10X, may be visible to the unaided eye, I3's inclusions may effect the stone's durability.
