The Blood Diamond movie is actually a good movie. I don't like DiCrapprio and such, but I must admit that the diamond market deserves this movie and that he acted well.
Perhaps my working in the wedding business for over 20 years has something to do with mydisgust over diamonds. They're for wimmin's egos and little more.
Diamonds are superd materials. They are very useful in lots of technology, even precision cutting tools as relatively low technology. Their great heat resistance makes them even sought for heat-resistant epoxies. Good diamonds are beautiful, but the ugly as well are terrific engineering materials; they aren't just for WOMEN (thank you very much).
