Petite X Ring in Sterling Silver with 18K Yellow Gold

My mother loves David Yurman. She has many pieces from DY from Nordstrom. I got us both these rings for Christmas as we are apart often during the year. The way her hand and my hand reacted to this ring -- something is off with Yurman quality now. Absolutely awful. We took the rings to Yurman in Texas at their storefront trying to replace for others to hopefully, keep them, but they wouldn't even acknowledge the rings. So, either someone is selling frauds or Yurman knows what they are doing. Within 15 hours of opening on Christmas, our fingers were swollen and green stained. We both had allergic reactions. I have no idea if this is a mislabeled or slanderous marketed ring listing as Sterling Silver... Regardless, it is clearly not Sterling Silver. The sizing is all off. Go up a half size. Or heck, don't risk it at all. :) We are returning as we had to work a miracle to get them off of our swollen fingers.
