i would only buy from a hong kong jeweler that i was referred to by someone i trusted completely and even then i'd have reservations. even if the jeweler showed gia certs, they could be counterfeit. my mil knows a guy that sells counterfeit rolexes in hk but charges retail and has the "certs" to "prove authenticity". his customers think they're getting the real thing. fakes are rampant! be careful.
