Would you go for a f coulour princess cut diamond with si1 clarity or a g with vs2 clarity?

I would always go with a diamond with higher clarity since there are less levels and more of a difference between each. G is still a good color. Are they comparable price?

However, you can really only compare them if they are graded by the same company.

You can find a lot of great info about color and clarity on the GIA website too.
