rhodium plating - is my jeweler telling me the truth?

Hello everyone,

I just picked up a white gold ring this afternoon after having it polished and rhodium plated at a new jeweler. I recently relocated, so I had never been to this place before. When I first saw my ring, I thought it looked a little darker than before, but I figured it was just the lighting in the store. When I got home I placed it next to another rhodium-plated white gold ring and realized it really did look dingy. So I took it back and told the jeweler what I had noticed, and he offered to "see what he could do." He came back after several minutes having replated the ring again.

I can't tell if the ring actually looks better now or if it's just wishful thinking, but it's definitely still darker than my other wg rings. The jeweler told me that perhaps the first time he plated the ring, "the heat was too high" which resulted in it looking darker. He also told me that sometimes rhodium from different suppliers has slightly different shades. Is there any truth to this?

I've never heard of different shades of rhodium before. I have heard of rhodium being contaminated, causing it to darken, but he denied that when I asked about it. To be honest this ring is not a very expensive piece (ok, I confess, it has cz in it... you caught me!), but I still think it's pretty and want it to look nice, and I'd hate to think he's blowing me off because it's relatively inexpensive or because he thinks I'm naive (a mid-twenties woman with a cz ring, etc... but I have nice jewelry too!).

Am I speculating too much? Any thoughts?
 
And btw, I've been wearing it since I got home, and the longer I have it on the more noticeable the color difference becomes. The ring used to look really bright and white before I took it there. Now it looks more grey and dingy. The shade difference might seem subtle at first, but it definitely gives a whole different look to the ring... and not in a good way =/
 
Yeah that's pretty much the effect I'm seeing! It's slightly different because this isn't a solitaire ering so the difference isn't so bold, but that darkish cast to the metal is really similar.

In that thread, it sounds like the old rhodium needs to be sanded off before the ring is replated. I doubt he could have had time for that when I took the ring back to him. He was only gone a few minutes. Can you plate over rhodium without taking the old rhodium off?

And does anyone know if the other explanations he gave me make any sense? I didn't see anything in the other thread that suggests that more than one shade of rhodium exists. I'm trying to figure out how much I trust this guy. I definitely won't bring any of my nice jewelry there, but for minor things he is really close and convenient.
 
I've never seen or heard of more than one shade of rhodium. It's all pure uber-white, at least that I've seen. And rhodium plate isn't an alloy... it's just a very very thin coating of pure rhodium, at least from what I understand.

I have heard that you can muck up rhodium plating however. By not cleaning the ring well, or having the rhodium mix dirty or whatever. (Clearly a techinical term there! :roll: )

So, I'd say that your jeweler just didn't do a good job. And that his explaination doesn't make much sense.

However I'm no jeweler so maybe one of the pros here will have a concrete explaination.

I had a rhodium plate job come out a bit wonky- it just barely whitened the setting, with the cream color of the 14K white gold showing through slightly. I assumed that was a poor job, probably from not cleaning it well; but, the jeweler who did it for me is a friend and did it for free, and I liked the slightly off-white look anyway, so I never said a thing- except thank you.
 
I think there is some mixing of chemicals that has to be done before applying rhodium plating, and I think the ring needs to be polished first.

It dosn't really matter what went wrong, if it looks crappy either ask him to do it again at no charge or ask for a refund so you can have it done elsewhere. IMO he probably knows he mucked up and dosn't want to admit it.
 
For clarity, could someone (in the trade, perhaps?) just clarify whether rhodium plating needs to be removed in some way (sanding, chemical removal, whatever) before a new coat is applied?

Just something I've not seen a definitive answer to in this thread, yet, and I am very curious. :halo:
 
Yes I'm curious about that too. The ring had been polished and then rhodium plated when I initially left it there, and then I believe he applied another coat of rhodium over the rhodium that I was complaining about. Would it make any sense to do that?
 
Rhodium can get darkish when it has become less pure. One must keep the solutiuon pristine or the color will be less than full white, and bright.

Yes, in order for the rhodium to really pick up one must give it a good polish first. Then, depending on the gold, a few extra dips are required for the plating to really stick. Unfortunately, a lot of jewelers like to skimp on the dips in order to save solution.

Also, as David mentioned, the solution must be kept very clean. If, for example, a jeweler dipped a silver piece in the same solution he uses for gold, it would cause it to become darker.
 
I appreciate your reply, Mark - thank you for the info.
 
No problem, good luck with your ring! Ask your jeweler to re-dip it again or you just might be better off taking it somewhere else... :cry:
 
Been away for a couple days, but I just wanted to say thanks for the info! I'll probably just end up going somewhere else. He didn't seem too open to discussion about it being dark, so I'll just count this one as a loss and go elsewhere in the future.
 
Rhodium solution needs filtering from time to time.
The pre-cleaner salts that is used first, and the rhodium are all required to be at the right temperature.
The solution ages and needs replacement - could have been near the end of its life.
There are black rhodium solutions (used for balck and champagne diamnds) and who knows - some one might have used the wrong one?

Ask them to fix it.
