This is really soft and even dents with use. The metal hardness with this mix is only 60HV. Possibly having a rhodium plating on the ring would keep patina from occuring, but rhodium plating on platinum is a no no unless it is 950 Platinum with Palladium. Maybe it is too soon to tell with our rings, I really don't know! Come to think of it, my wife's wedding band is high polished and is made of 950 Platinum with the 5% being Ruthenium, and hers shows no sign of patina yet, either. It could be the S1 mix is helping that, being the 5% S1 mix creates more hardness factors in the platinum, or that my ring's hammered finish is very high polished. The only thing I do to keep it clean is shower with it on every day. I have been wearing my 950 Platinum S1 wedding ring every day and all day since I got hitched last September of 2003 and it has not developed any patina yet and is still shiney new looking.
