Best ring I ever found was in Aruba in Feb of 2005. Was down there with my family for the week. Our departure flight was delayed a full day (broken plane), so I was in the water @ our hotel with my surfmaster pi.
I heard someone coming up behind me... I was just about chest deep in the water, heading back toward the beach. An older lady (mid 60's i was guessing) asked me if i could help her find her sister's ring. she had just dropped it and was standing right around it. I looked up, and right in my projected path was the other woman... waving at me. I went over, introduced myself, etc.
I did a circle pattern spreading out from where she was standing... and sure enough about 5 feet away from her i got a hit, and scooped it up. As I did, i looked down and started to pray that this wasn't her ring. It was big, VERY shiny... i could see glints, and glitters and white, and red and gold. I asked her to describe it for me and she responded, almost instantly (I can still hear her voice in my head when I tell this story)
"Oh... Its got a large diamond in the center, and that's surrounded by a ring of rubies. 10 I think. And that's surrounded by another row of small diamonds. He bought if for me for our 50th wedding anniversary last year. He got it right here in Aruba, down in Oranjestaad. He got a great deal... He only paid 26 THOUSAND DOLLARS."
I still want to cry when I tell that story. The husband was nice enough to offer me a reward, which I declined. I guess the good karma will have to be enough. What kills me is that she was right in my path, and she said that she and her sister were just getting out of the water when she noticed the ring was gone. Timing apparently is everything
