These earrings are gorgeous and I purchased 3 different colors. I absolutely love this style screw back. They are so much easier to put on than any other screw backs I've used and I love how they styled the backs with a stone so it looks like an earring on the front and back. I will say the backs do have some weight to them so I'm glad the earrings aren't too long otherwise the weight would pull them down on the lower soft tissue lobe piercings. So far I've had this pair in for over a week and showered in them and they seem to be holding up very well. No tarnishing no irritation and no green color. I've also been spraying them with saline spray twice a day because I just pierced the holes above these and even that hasn't caused any tarnishing so these are definitely very good quality. I'm thinking about buying more of these just to have extras. Highly recommend.
