That's amazing!! I have a heavy gold man's bracelet that I found years ago at the mall. The clasp was broken, which is why it was lost, I suppose. I reported the loss to mall management, but no one claimed it so I just kept it. I've often wondered how much it's worth. It's at least 18k gold, might be 22k. I guess after reading your story, I should get the thing looked at and find out how much I could get for it!
