Ideal/softest metal for ring holder necklace?

[ECMO]

My girlfriend needs to wash her hands and wear sterile gloves a fair bit at work, and as such she can't actually wear her (Pt950/Ru) engagement ring for most of the day.

I'm looking to get a wishbone style ring holder necklace, and I've been looking online at which the metal of choice would be, but there is some conflicting information online.

Essentially I am looking for a white coloured metal that when rubbing against the platinum/ruthenium ring will be eaten away and not eat away the e-ring

I've already ordered one in Sterling silver but it didn't cost that much so if 14k-18k white gold is softer and more protective for the platinum ring then I will get one of those instead.

Pic related, it's the one I ordered

I would probably do 18kt gold.

You can also just put the ring on a necklace as a pendant without a holder. Just slip it on a chain. That works well.

I would not trust my engagement ring on a delicate chain.

Easier just to get a solid chain.
Best to choose a soldered link chain of decent gauge.
A parrot clasp is better than a ring bolt clasp.
Avoid box chains and the like, they can and do break.
Keep chain length short ie under 18 inches. She doesn’t want to be bending down and having it “swing out” and “crash” into something or someone.

Ok I will look into getting a separate chain that is a bit more robust.

Are you saying a soldered link chain in addition to the holder or just the chain by itself?
