Just right
I purchased the Gold in 3mm and 2&4mm for Silver. The 2 & 3mm almost has no difference in size and looks. They were too small, so small that I don't know what's the sense of that. I prefer the 4mm. Enough to consider as "tiny" earrings. The 4mm is yeah small and can still add something to your look. I just gave those 2&3mm to my daughter.
