I agree with those that say that the pride of the sons of Feanor and Feanor himslef are the main cause for the war. But when you think about it, these jewels are beyond price. The obviousley can't be made agin or else Feanor would have just made more. These things represent everything that Feanor worked for and his pride so when they were stolen from him he went nuts, and his sons followed him.
