There are different systems to grade the quality. I'm too far out to remember the specifics, but there are two that are commonly used, and reliable. There's a third that is notoriously generous in its ratings, and most B&M places refuse diamonds with those certifications. BN and other online vendors won't hesitate to sell you those diamonds.
i found it a LOT easier to find gia and ags certified stones online. i saw a LOT of egl and igi (and a whole lot of other random ones) in b&m stores, including many stores with NO gia certified stones.
