I bought the warranty and I am so glad I did. Each time she wears it a diamond falls out. So we take it back every time and they keep it for about 2 weeks and replace the diamond that falls out. Each time she gets it back she wears it for a few days and another one falls out. Well this last time we got it back and the yellow gold is now almost “wearing off” by the clasp and the diamonds that were replaced look darker and not as clear. I am fed up and want to just return, but am worried they will try to give me store credit or not take it back because to fit my wife’s wrist they had to take a few links out. Any suggestions on what my approach should be with them?
