First thing, these are the easiest earrings I have ever put in my ear. The style makes it so much easier than a screw-in style. You just push the front into the post. So I did make a mistake in ordering, and got the smallest gem size. I have an unfortunate issue from a history of wearing bad jewelry when I was young, and the front of my piercing site is a larger size than the back of the piercing site on my lobes. This jewelry does sometimes get pushed into my ear because of this. I ended up putting one of the studs in my helix piercing though, and it looks amazing. The opals are so shiny and catch a glimmer even in dim lighting. The quality is amazing, and I am actually probably going to purchase this set with a bigger gem size.
