The wife: These are fine. I actually ordered up a size to replace the smaller size I purchased previously, so be sure that you look at the measurements and do a search to see what that looks like on an adult ear. Note that it is not completely round but more of a dome shape which his okay once it's on your ear but looks a little strange out of the box like um, why are they flat in the back? Also the Fastener is plastic with a gold (I hope) hole in the center to insert the post. I haven't seen that before but I wore them about 7 hours and didn't have any irritation. With pearl earrings either you like pearls or you don't, so the only thing left in the end is they seem good for the price. I bought them to wear to an event so I will update after using them for work several times if I find any irritation to my ear.
