No difference in small to medium size
I ordered these twice- first the smallest mm size offered. I received that pair and though well packaged found they had clear glue dried on one of the earrings making it appear lopsided and not round. I returned that pair and ordered the next size up, that pair arrived in good condition (well packaged again, and without glue), but the size was the same as the first pair in the smaller mm- no difference between the two. The next option up is the largest size that is no longer round, so time to look elsewhere for what I had in mind. Quality is good overall, but I would say more of an $11 earring than a $20. I do appreciate the thoughtful presentation box and note.
