I actually received these pearls as a birthday gift, and I can say with certainty that the set I received DOES NOT have large bumps in the pearls as a previous reviewer suggested.  As a freshwater set, they do have little imperfections, but that's what makes each one unique and distinguishes it as a genuine pearl.  I love this set, and would gladly recommend it.
The color and shine is very nice, and the length is perfect for most outfits.  It even came with a cute little box and fabric case.
The only issue I have had is with the clasp.  After a few weeks of wear the clasp started sticking in the open position.  I have since had it replaced, and have had no further issues.
Overall, it's a great necklace for the price.
