These earrings are gorgeous. I didn't think I'd love them so much because they're so simple, but I think these have slid into my favorites list. They're light and small, which makes them easy to wear on the daily. Because of the separate pieces, they do jingle a bit if I really shake my head or jump around, but for most daily activities I just hear a slight rocking sound if I'm paying attention, and that's it. The size is great because they don't catch on things easily, though the points are sharp, not so much that they'll hurt you (trust me, had to test that because I've got kids and one is a cuddler), but my little has reported they're a little "pokey" if he leans on them wrong. Thankfully, because they're free-hanging and so flat, most times they'll just press flat against me and it's not an issue. Because this is starting to become a trend in my reviews, yes, you can comfortably sleep in them! They're so light and the multiple pieces had me worried, so I had intended to take them out before bed, but I'll own that I fell asleep watching YouTube and woke up a good 6 hours later. I am hesitant to make a habit out of them because I am a bit concerned that they may come apart as I'm not a gentle sleeper and the rings could potentially get pulled apart, but they hold up really well.
