The VVS2 grade is a very high clarity rating where the diamonds are “almost perfect”. This also happens to be the grade where you’ll see huge price premiums kick in because the rough crystals are very scarce in nature.
At this grading, inclusions are so insignificant that it is difficult even for a trained gemologist to detect them under 10X magnification. Needless to say, diamonds in the very very slightly included (VVS2) grade will always be eye clean.
When I first started out in the gem trade, I had a hard time detecting inclusions with hand-held 10X loupes. I had to “cheat” by using binocular scopes to inspect the diamond at 20-30X magnification. After detecting where the inclusions are located, I would turn down the magnification back to 10X and verify them again.
Of course, with practice you’ll get better overtime and become more familiarized with identifying inclusions. However, till this day, it would still take me a few minutes of careful examination to map and correctly identify inclusions in a VVS2 diamond.
The point I want to bring across here is: if a trained eye can have difficulties in locating inclusions at this clarity rating, a layman would have an extremely hard time doing so with a loupe. As a matter of fact, 99.99% of consumers can’t tell the difference between a VVS2 and a VS1/VS2 diamond when they are placed side by side.
First of all, inclusions in both grades are very difficult to detect. However, the main difference that sets VVS1 apart from VVS2 is how obvious the inclusions are when seen from the face up view under 10X.
As a general rule of thumb, the inclusions of a VVS1 diamond are usually only visible from the pavilion side (bottom up) under magnification. For VVS2 stones, inclusions are visible in the face up view and typically located in the top half of the diamond.
VVS1 vs VVS2 Clarity
* For extremely large diamond sizes (e.g. 1.5 carats and above), VVS1 diamonds can have inclusions that can be seen in the face up view when inspected under magnification.

Can you see the inclusions under the 20X magnified photographs? I definitely can’t and I don’t think you can either. You see, that’s the thing about VVS diamonds, they are so clean that inclusions will only show up under the correct viewing conditions. Plus, it takes a trained eye and some experience to find them.
Clarity is just a single aspect of the 4Cs. Remember, there are many other factors that contribute towards a diamond’s overall appearance and beauty.
