I know this is from a while ago, but I was wondering how you contacted the New York Cartier about them rhodium plating the WG love bracelet (no diamonds).
I have been trying to find which place said that they could do it, but so far they have said they can't and wasn't sure where or how to contact.
I want to preface by saying I have zero experience with this issue through a Cartier store.
That being said, the rhodium plating process is very straight-forward. I've had a Gabriel and Co ring replated over 14k WG multiple times over the years by my local jeweler. It feels like the cost of plating gradually goes up every time, but it's still a super quick and inexpensive way to make WG shine like new.
If you really want your bracelet plated, and have a jeweler you trust locally, maybe just have them do it? I can understand wanting to stick with Cartier bc that's where you purchased your bracelet, but I've heard REALLY mixed things regarding their customer service when it comes to having work done on Loves (polishing when it wasn't desired, ridiculous lead-time for repairs, fixing loose screws that just come loose again, etc). If something was BROKE, I would be more compelled to stick with Cartier. Not so much with plating, just my 2 cents!
