Jennifer Connelly has admitted she will never enjoy diamonds again after making her latest movie.The 36-year-old actress, who stars in 'Blood Diamond' alongside Leonardo DiCaprio, says she was shocked to learn that the conflict diamond industry in Sierra Leone funds civil wars and uses child soldiers.Jennifer said: "I didn't know what conflict diamonds were. It's impossible for me to look at diamonds the same way as before."The 'A Beautiful Mind' star says she doesn't have to question the origin of her engagement ring from Paul Bettany - who she married on New Years Day 2003 - because she doesn't have one.She said: "We just have these very simple gold bands."But these earrings are Bulgari diamonds. They came with a certificate. The more people insist on that, the more the diamond industry will have to work to close these loopholes."
