Nice earrings
Color: Silver, Size: 24 mm
These earring are beautiful. I like how they sparkle. They are very comfortable. I gave them 4 stars because I feel like the clasp closure is a bit loose. It still closes but I noticed one closure is looser than the other. I love the size of them, They are not too big but they are not small either. I feel like they are the prefect size. I like the thickness of them and make a great statement piece. I get compliments on them. I recommend.

Heavy Earrings
Color: Silver, Size: 19 mm, Color: Silver, Size: 19 mm
While quite beautiful, my wife complains that they are a bit heavy for her ears and cause her pain. The inner glass circle is removable and has helped alleviate the weight on her ears. However, that was the reason she chose these earrings. If she takes that off, she is left with plain silver hoops, which she didn’t want.

very pretty, sparkly
Color: Silver, Size: 19 mm, Color: Silver, Size: 19 mm
These actually look much nicer than I thought they would, given the price point. These ae silver plated brass, but nickel and lead free. It is kind of a bummer that they are only silver plated though. So far, they haven't been irritating my ears at all.
They open really wide with a hinge at the bottom. The little sparkly donut covers that while you're wearing them so you don't' really see the hinge. The donut can slip off very easily though. You have to be careful when opening, closing, and putting them in.
