Thus far the stones I have been looking at have been SI1 in clarity. However, should I really look into VS2? Is there that much of a difference? All I want is an eye-clean stone (part of my issue with buying online, I can''t see it myself!). Should SI1 be sufficent as long as I look at the stone and make sure I can''t see anything or should I go for the VS2? Also is it possible for a VS2 to not be eye clean?
