    Since you don't tell us whether or not you have any gemological
    equipment it is hard to tell you what to do to identify the stones. 
    It would probably be best if you found a knowledgeable gemologist in
    your area and pay to have them appraised.  On your own , what I can
    tell you is that if the stones appear to be perfectly cut (no rounded
    bellies, even sizes, 10mmx8mm, 8mmx6mm) and have perfect six rayed
    stars, the odds are that the stones are synthetic.  However it is not
    a guarantee that they are synthetic with these conditions, it is just
    that the odds go up.  Better to see a gemologist.
