How to oxidize palladium


#1

Hi,

I am about to make the wedding bands for my fiance and I. My ring
will be a combination of yellow gold, pink gold and palladium while
her ring will be most palladium with some green gold. I’ve never
worked with palladium but she wants me to oxidize parts of it to
make it look like nighttime. The green gold will be in the foreground
(mountains) and the palladium underneath and in the background
acting as the sky. I’m just wondering if palladium can be oxidized
like the way liver of sulphur will blacken silver. I’ve read iodine
can do this for identification purposes but I wasn’t sure how long
term this is. Any tips would be appreciated (September 1st is the
wedding date…)

Thanks!
Adam

Palladium is very chemical resistant it will not color like silver,
but patinas are a bad idea on wedding rings anyway as they will not
stand up to daily wear.
