Diamond Clarity
Practically all diamonds contain naturally occurring internal characteristics called inclusions. The size, nature, location and amount of inclusions determine a stone's clarity grade and affect its cost. Clarity is dertermined using 10X magnification. By definition, if something is not visible at 10X, it does not effect the clarity. | Flawless | VVS1 | VVS2 | VS1 | VS2 | SI1 | SI2 | I1 | I2 | I3 | | 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= Noticable, relatively easy to find under 10X. Not visible without 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. |
