SI 1 cleanliness
SI 1: Small flaw1-Professionals can easily observe obvious flaws at the magnification of 10.
SI2 transparency
SI2: Small flaw level 2-Professionals can easily observe several obvious flaws under the magnification of 10.
Diamond clarity is divided into fl \ if \ vvs1\ vvs2 \ vs1\ vs2 \ si1\ si2 \ i1\ i2 \ i3, and the clarity decreases in turn, as follows:
1.FL Transparency
FL: Flawless-professionals observe under the magnification of 10, and there are no flaws inside and outside. This diamond is the rarest of all purity grades.
2. If it is clear
If: flawless interior-professionals observe under the magnification of 10, there are no flaws inside, but there are tiny flaws on the diamond surface.
3.VVS 1 cleanliness
VVS 1: Very tiny flaw1-At the magnification of 10, professionals only observed a tiny flaw.
4. cleanliness of 4.VVS2
VVS2: Minor defect level 2-Individual minor defects were observed by professionals at the magnification of 10.
5.VS 1 cleanliness
VS 1: Flaw1-Professionals can see a single tiny flaw at the magnification of 10.
6.VS2 cleanliness
VS2: Defect Level 2-Professionals can see several tiny defects at the magnification of 10.
7.SI 1 cleanliness
SI 1: Small flaw1-Professionals can easily observe obvious flaws at the magnification of 10.
8.SI2 cleanliness
SI2: Small flaw level 2-Professionals can easily observe several obvious flaws under the magnification of 10.
9.I 1/I2/I3 cleanliness
I 1/I2/I3: obvious defects-obvious defects can be easily seen without a magnifying glass.
