Be very very wary, my mate sells replica Rolex watches, they are identical and all come with paperwork etc..... but they're only worth a few hundred quid........... she sells them at a few thousand ££££ each!!!!!!!!

Personally without paperwork i'd tell the bloke to run and jump, and even with paperwork, I dont think I would agree as it is very hard for jewellers to even spot the fakes from the real ones.
