authenticate a clasp? I think someone one craigslist ripped me off!

[adiorandomhero93]

Ok so about 3 years ago I bought a Rolex from some guy on Craigslist and I know the case and movement are fake. I'm pretty sure the band is too unless Rolex makes a goldplated jubilee band. But I'm not sure about the clasp because it has all the correct markings and I can't find anything wrong with it..I'm just trying to recoup a $500 loss and sell any part of the watch that is authentic. I know I should have known better...is there anyone kind enough out there to help me try to authenticate a clasp? I would appreciate it so much, Thanks guys!!
