[/quote]Now in light of the approaching depletion of the diamond mines, it's a great idea to use diamonds for the underlying asset.But what kind of diamonds are you talking about? Are  a diamond as  a raw material or a jewelery-cut diamond? Do your diamonds have a certificate and in which center was it obtained?
