I thought it was just a freak occurance when one of the stones fell out.. I got lucky and found it and put it back in securely. Then, 4 days later, a different stone fell out... this one I was not so lucky on and could not find. It is a beautiful ring- I loved it, but at this rate, there will be no stones left in a a few weeks. I'm contacting overstock- obviously the prongs on the settings are not big enough or secure enough.
