I bought two of these rings to stack them around another ring.  They were thinner than I expected but still quite nice.  Nice shine to them until I put my hands into bleach water!!!  WARNING...don't get sterling silver products near bleach!!  The rings tarnished IMMEDIATELY...after I used some serious elbow grease to rub them with silver polish, I was able to get them to look somewhat normal again but the shine is GONE.  Not the fault of the product or the seller, just a warning.
