The clarity level of a diamond ring is classified based on its contents and flaws. According to the GIA grading standard, it can be divided into FL (flawless), IF (flawless inside), vvs (very slight), vs (slight), SI (minor), and I (heavy). FL is flawless, IF is flawless under the mirror, vvs has very, very small flaws, vs has very small flaws, si has small flaws, l has serious flaws, so the closer to FL, the better the clarity of the diamond.
Diamond ring clarity level
1. FL (flawless level): The diamond grader observes under a 10x magnifying glass, and there are no flaws on both the inside and outside of the diamond;
2. IF (Internal Flawless Level): Although there are no flaws inside the diamond, there are very small flaws on the outside that can be removed by re polishing;
3. VVS (Very Minor Flaws): divided into VVS1 and VVS2 levels, diamond grading technicians find it difficult to detect extremely small or inconspicuous flaws under a 10x magnifying glass;
4. VS (Minor Flaws): divided into two levels, VS1 and VS2, the size, quantity, and location of flaws under a 10x magnifying glass by a diamond grader are between difficult to determine and somewhat easy to determine;
5. SI (Minor Defect Level): Divided into SI1 and SI2 levels, significant flaws are easily visible by diamond grading technicians under a 10x magnifying glass. When the diamond of SI2 is observed from the pavilion side, the inclusions can be seen with the naked eye;
6. I (Defect Level): divided into three levels: I1, I2, and I3
I1： The diamond grader can easily see it under a 10x magnifying glass, making it difficult for the naked eye to observe from the crown. Internal flaws do not affect its brightness;
I2： Internal defects are large and numerous, visible to the naked eye, and affect brightness;
I3： The internal flaws are extremely obvious and affect the brightness and transparency of the diamond.
