Loose rough, uncut diamonds for sale and auction, all sizes available, including canary yellow diamonds.  These rough diamonds are the raw mineral, as it is when it is mined.  While these stones do not carry the same face value as a finished and cut diamond, the potential is stil there. You could buy these very cheap, and then have them cut an finished by a gemologist.  Or buy them in bulk as an investment and sell them in their rough form individually.
