USA Today reported a diamond robbery in Brussels Airport. The diamonds consisted of both rough and polished. The authorities are not disclosing the exact amount of diamonds stolen but $50 million is the speculation. Its almost impossible to trace rough diamonds, the thieves will probably have them cut in India, Israel, South Africa and the US and have them fitted into the system. It is a bit harder to resell polished diamonds as they have a fingerprint. Go online for more details, its a crazy story-like it was taken out of a movie.
