The stone is clear, sparkly and well set.  I think it looks real.  I even asked some people, "Do you think this is real?"  They said yes.  In retrospect, I asked polite people who probably would have said yes regardless of what they thought.  Maybe I will ask some rude people.  Rude people will tell you what they think.  Or maybe I will not ask anybody.  I like it and I'm happy with it so I will just be.  One thing I am not so happy about is the chain.  It looks fine, but the clasp keeps working its way to the front and hanging with the pendant.  When that happens, it does not look real.  Real diamonds of that size come with chains whose clasps know that their place is in the back.  If I can find another silver chain, I will take care of this problem.
