A ruby ring. We used to cash my husband's paychecks at a pawn store because it was the cheapest way to cash it and we didn't have a bank account back then. The pawn store would let you buy things on payments if you were a good customer. I had my eye on a gorgeous, large ruby ring and in the weeks just before Christmas it disappeared out of the jewelry case.
Come Christmas morning I opened a large box that had another box that had another box that had a small box. My ruby ring!! My husband had literally bought that ring behind my back!! He said he was standing behind me and just nodded at the clerk that he wanted it.
