I'm not sure how to do this review.  My hubby and I got a matching set.  His the 8mm, mine the 6mm.  They are beautiful and seem to be made very well.  Mine fits well and I couldn't be happier.  No problems.  However my husband isn't thrilled with the ring itself.  He loves the looks but his seems to have a sharp edge that could very easily cut your finger if it hit your finger at the right angle.  We were a bit disappointed with that part because the rings are gorgeous.
