Hi there. I have some sterling rings I just bought from a vendor (we will call them Vendor A) and they are turning customer’s fingers green. These same customers are wearing other sterling rings that they have had for years AND they have now tested new ones from yet another vendor (Vendor B) and their personal rings and Vendor B’s rings haven’t discolored them at all. These are people that wear only sterling and we aren’t just talking about a few, I have feedback (and green finger pix) from about 25+ people. Vendor A’s rings were tested and show to be true sterling. So for the life of me (and the life of Vendor A’s) we can’t figure out why one sterling would discolor and the other not. Why would people who have always worn sterling suddenly get discolored from Vendor A’s rings? I have never had this happen before in the 15 years I have been selling sterling rings (bought from at least 6 different vendors).
Further info, Vendor A is USA based and had their sterling tested here as well.
