I've been commissioned to remove a stone setting from an 18ct white gold ring & put in a new setting with a different stone. However I've found that the 18ct white gold I have for the new setting is much darker than the ring, which makes me think that the ring is rhodium plated.

If I solder/pickle the ring, will it remove the rhodium plating to reveal either 18ct yellow gold or a dark 18ct white gold underneath?

I'm wondering whether to offer to remove the rhodium plating altogether - can this be done by filing alone or does it require a kind of reverse plating process?

I don't plate jewellery & don't know the first thing about it so re-plating isn't an option without contacting another jeweller to do it for me.

Thanks
