I would take them off, clean them good, put triple antibiotic on my finger until it seemed to heal, then put the
rings back on and the same thing would happen (a reddish rash under where the
rings touched my skin). I have a ring on my right hand that this did not happen with, and I noticed that the rash was confined to the area where the diamonds were (so bacteria could have accumulated there due to moisture and caused a form of athletes foot).
