My fiancee and i bought a white gold engagement ring and male wedding band. Within 3 days 2 stones fell out of the engagement and one out of his ring. We went back in and he basically told us it was our fault and wasnt going to help us. No refunds and laughed at us. We went to the jewelry store down the way and they said many folks have come in crying because of how these guys ripped them off
