Platinum Tarnish Q

#1
Hello,

I am making a box for my platinum engagement ring, and I want to use leather to hold the ring in place. The leather would physically contact the ring’s shank.

I know that chemicals from the leather’s processing can tarnish many metals. I also know that platinum does not tarnish easily.

Does anyone know if it is safe to allow leather to be in contact with platinum for (possibly) prolonged periods?

Thank you!
