Query: Don't buy from ARMY Universe

The stone fell out of this ring about 5 weeks after it was received. Apparently it had exceeded the 30 day return date, but Army Universe agreed to correct the mistake. The ring was returned to Army Universe at my expense. Army Universe claims to have repaired and returned the ring, but the returned ring has never been received. Not a high quality ring because the stone fell out and I will never order from Army Universe again. They refuse to correct the mistake.
