Yes, twice! All my life I'd wanted a diamond because it was my birth stone... When hubby and I got married he bought the biggest diamond we could afford (not terribly big!). One day while cleaning house for my mother, the diamond fell out of its setting. We all searched the house, my dad even tearing apart the vacuum cleaner bag and combing through every bit of dust and dirt that was in it! No diamond. So several years later we were able to buy an even better and slightly bigger diamond and had it set in my ring. The jeweler made sure it was good and secure and would not fall out of the setting, as the first one had. I was very proud of that diamond... until one day, working with a horse, the entire setting fell off, diamond, prongs and all. Searched the area but it was hopeless as the horse area was pretty soft and muddy. After that I gave up on diamonds and now wear a plain gold band. I'm just as married without a diamond!
