Which platinum alloy does David Klass use?

Does anyone know?
I would ask him myself but I've been sending him so many emails I honestly don't want to be any more annoying than I suspect I already am...

Also - is there a colour difference between the various platinum alloys? I have a wedding band that is stamped PLAT and when I try on modern platinum rings in my local jewellery stores they always seem more grey and mine seems almost more creamy?

Gosh. Good question. I’ve had him make me several platinum rings and I just went back to my emails to check and he never says. I never asked either.
I will say they have held up very nicely imo.

I don't believe there is a lot of color variation in platinum alloys - just hardness and toughness options.
What you see is probably more about the difference between worn, polished and rhodium plated versions.

David told me that he uses 95 percent platinum & 5 percent iridium, nothing else in the metal.

To be sold as platinum it must by laws be minimum 95%. That is why there is little chance for the other 5% to change color, just working and durability properties.
