Unlike the diamond “cut” grade, the diamond clarity grading system is fairly easy to understand and applied consistently by different certifying authorities. The clarity grades are as follows:
• F (Flawless): for diamonds with no external or internal flaws
• IF (Internally Flawless): for diamonds with no inclusions and a small number of blemishes
• VVS1-VVS2 (Very Very Slightly Included): for diamonds with a small number of inclusions that are very difficult even for gemologists to see under 10x magnification
• VS1-VS2 (Very Slightly Included): for diamonds with internal flaws that are difficult to see under 10x magnification
• SI1-SI2 (Slightly Included): for diamonds with inclusions that are easily seen under 10x magnification
• I1-I2-I3 (Included): for diamonds with inclusions that are visible to the naked eye
