I wear these on stage, and they look great. The little ones could pass for diamonds. I like having the different size options to put in multiple piercings, and not having to worry if I lose one. I wish the backs were more secure. They don't always stay on straight with the post straight through the butterfly clutch. And the large ones tip down unless I use supportive backs made to hold up big earrings. But I've had no problems with metal on my sensitive skin. I thought I could only wear high karat gold, but these are great.
