I have a care plan with zamels for my engagement ring.
it's 18 crt white gold, so I understand that you have to get it rhodium plated which is fine, I do find my ring requires this quite often. and the last 2 times I have got it done I was not happy. they send it away to get done and when I get it returned it still is a yellow tinge to it, I have to get it redone and it goes a tinged colour within a month again, last time I got it don't which was a couple of weeks ago I explained my wedding is coming up and I really need it done properly, they did it I got it back and could tell straight away it was still a yellow colour and still was not cleaned properly I compared it to my wedding ring and it was a noticeable yellow.
I ended up having to take it to heirloome jewlers which cost me $125 to get my ring done properly.
it's very annoying to have to pay for this when it is included on my plan.
