Unless you plan on using these for another item besides stud earrings some day, SI1 at least would be relatively eye-clean. They're on your head though, and not many folks will get close enough to check them outAme what does that mean exactly, the table?
As for clarity - wow, I would have thought no one here would go for SI's!! My original engagement ring had excellent cut and F colour but was SI 1 or SI2, and you could see black carbon bits in one corner - it really bugged me. I know they're small and earrings... am just worried about whether they will be eye clean or not under VS2. Am just going by my former research for my new e-ring and on blue nile's guides.

The table percentage of 55 is kind of a magic number. 55-56 is particularly an ideal range. But 55 is like the middle of ideal range for the table. The numbers across the board for that set appealed to me.
See what you can find in SI clarity though before you just jump in.
