WOW! What a close call. No, I take that back. It's a sign that you are SUPPOSED to have this bracelet. I am so glad that all turned out well. I hope Tiffany's does a thorough cleaning and replaces the clasp with on that has a safety chain.
A similar thing happened to me. I was at the barn, looked down and noticed that three of the four prongs holding the nearly perfect .75 carat emerald cut diamond in my engagement ring were broken. The diamond was just hanging there. Hummmm I took that as a sign too -- DO NOT WEAR DIAMOND TO BARN
