I was looking for a thumb ring that wasn't too gaudy. I wanted a band, but also something with a little edge. I decided to go with this zig zag band. I am so happy with my choice! It's very sturdy and made of good quality! I'm a serial hand washer and I wash my hands countless numbers of times throughout the day. This ring has to be sterling silver because it hasn't turned on me, and I don't expect it to! I wanted to wear the ring for a while, and give it some time before I posted this honest review. Not one bad thing to say about this! My 3 photos should give you a look at the ring up close. I would also recommend that you Google "printable ring sizer" before making a purchase so that you can order your correct ring size. Fast shipping and affordable prices! Thank you!
