If I could wear them , they'd be 5 star. Like others stated the loop part (circle) is small and the part that goes in your ear is thick,
With that said, I believe the issue is more individual based. My ear pierce is middle/high on my earlobe. These require a middle/low
pierce on the earlobe. I'm a healthy adult with what is considered average sized ears/earlobes.

Bought both Black/Silver and Sapphire/Gold . Both unbelievable quality for price. Come in a little gift box- with a bow!
Black/silver has matte finish (less shiny than pictured) but this adds to the piece not detracts. If shiny it'd look like cheap glass.
Blue/Sapphire is shiny and that adds to the piece. It looks real, like it's a stone w a nice cut. The gold was a little too gold tho.
