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 bought this bracelet maybe 2 years ago. It is my favorite bracelet to wear. The craftmanship is excellent. Looks as good as the day I bought it. I live in Boulder, Colorado, USA.
