Anyone with Platinum settings (halo) tarnished?

Does anyone think their patina of their platinum setting resembles tarnish from sterling silver?

High noble alloys of platinum (Plat/Ru and Plat/Ir) will not tarnish. Plat/Cobalt alloys seem to be becoming more common and will tarnish. Plat/Co has advantages for the manufacturer (cheaper and easier on tools) but IMO negate the main advantages of platinum to the consumer.

I'm pretty sure real platinum doesn't tarnish. Mine sure hasn't.

This is a strong statement on why platinum is preferable over white gold. It says that white gold can tarnish, not platinum.

When silver tarnishes it oxidises and goes black.

White gold that has lost its rhodium plating goes dull with a yellow tint, however, it does not go black.

I have not come across platinum going black with age.

Strangely, none of my platinum pieces have actually really developed patina. They look the same color as they did when I first got them.

My OEC diamond came in a very battered platinum fishtail solitiare setting that looked like gray or blackened, about like a piece of welding rod in color. Matte finish. Definitely not gleaming white. I don't know it's composition. I reset the diamond into anew setting.

Was trying to remember where I recently read that Plat/Co will tarnish, and it may have been here https://www.pricescope.com/journal/overview_common_alloys_used_jewelry but I also read this somewhere else. I was recently looking into it because the jeweller doing the insurance replacement of my Plat/Ru ring substituted Plat/Co without consulting me (thinking I wouldn't notice or care, I'm sure), and immediately upon seeing it I knew it was the wrong alloy - the ring was visibly bluer than my original - so much so that the diamond actually took on a blue tint simulating blue fluorescence.

Disadvantages of Plat/Co alloy to the consumer include that it may not be as hypoallergenic as the high noble platinum alloys are, it can take on a tarnish and for this reason plat/co is often Rhodium plated (eliminating the benefit that platinum shouldn't have to be dipped like white gold), it's ferromagnetic which platinum isn't (important if for example you work around MRI's), and the aesthetics of the blue tint which is readily appreciable even without tarnish if you are colour sensitive like me. I didn't get an E color diamond without fluorescence for it to look blue because of a cobalt alloy!

Sorry for the tangent, still a fresh wound from the argument with the jeweller over this

My other white gold setting turned yellowish tint. This one is pretty good. But I think I will go with platinum because i don't want to ever see any tint.
