Flawless diamond question

[pyramid]

Seen written here many times that a Flawless diamond is only Flawless at the grade of 10x magnification and if the diamond
is inspected at 20x magnification you would see flaws.

What type of flaws would they be, only pinpoints, or are there feathers and crystals at 20x magnification? What are the inclusions
called at that increased magnification?

I was just wondering because I have seen that some don't like certain inclusions, and yet don't realise,
that they could buy a VS2 diamond with a crystal inclusion because they don't want feathers. On the plot will be the
crystal as it is graded VS2. However there may be say two VS1 feathers in the same diamond which will not be shown. The grader only has to put on the plot what is calling out the grade. So they think they have no feathers and they have no VS2 feathers but they do have other smaller ones.

Well it is then the same with buying Flawless I would think.
