This is 950 silver and I have been wearing it for 6 weeks or so. Excellent craftsmanship and very pretty. I shower and sleep as well with this on. No tarnish. I do wipe it with soft cotton cloth few times a week. Will highly recommend this.
I like the three dimensional effect theses earrings have, and think they are going to be among my favorites. For me, the size is perfect. Very nicely made, wearing them as I write this!
