Movie that changed my perspective

In the movie blood diamond people are being killed in Africa so that rich people can have their diamonds. After watching the movie it really changed my thoughts on the diamond industry, i do not think that we should be buying diamonds until the blood diamond conflict is taken care of. The movie also shows that the diamonds are really not that rare, but the big diamond players control the price by keeping the diamonds off the market so the supply is low and the demand is high.
