Hi All,
I' originally posted this thread in the jewelry section ([URL='https://www.pricescope.com/community/threads/gabriel-and-co-platinum-palladium-setting-durability.190403/#post-3468604#p3468604']https://www.pricescope.com/community/threads/gabriel-and-co-platinum-palladium-setting-durability.190403/#post-3468604#p3468604[/URL]) but was recommended to move the thread to Rocky Talk as there are more traffic here for responses.
I'm close to purchasing a Gabriel and Co platinum setting for an engagement ring (and maybe the matching wedding band too), but I have found out that they use a 95% Platinum 5% Palladium alloy which has a Vickers hardness around 60 HV. That is slightly better than pure 24kt gold at 40HV, but softer than 22kt gold at 70 HV. Does anyone who have a Gabriel and Co platinum piece, or a platinum/palladium ring, speak about their durability and scratch resistance? I'd hate to buy a platinum setting only to have it scratch up easily over normal wear.
Ruthenium, Iridium, and even Cobalt would be a better alloy if I had a choice. Too bad Gabriel and Co won't use a different alloy (I've asked). Pt950/Pd is a soft material which is good for finer details in their designs, but I just don't want to end up with a nice looking piece that will turn to mush over time (Or worst, have the prongs open up and lose the center diamond!!! )
I could be over analyzing things and 60HV is plenty hard for jewelry. I am only going off of the info I've found regarding the other blends of platinum. Mark Morrell, one of the highly appraised designers recommended on PS, stated that even 950PT/Ir with 80HV is a very soft alloy "not resistant to scratching, bending, and being deformed and dented by impacts". (http://www.mwmjewelry.com/platinum_purity.htm) I am concerned about the 60HV, which is why I would like to ask for real world experiences with G&Co pieces and/or Platinum/Palladium alloy settings.
As a reference:
24kt pure gold is around 40HV
950Pt/Palladium is around 60HV
22kt gold is around 70HV
950Pt/Iridium is around 80HV
900Pt/Iridium is around 110HV
950Pt/ Ruthenium is around 135HV
950Pt/ Cobalt is around 135HV
