Do you think these are real?

[la_corsetiere]

I recently purchased these 12.3mm round "Tahitians". When I received them, they looked absolutely perfect, gorgeous mirror luster, exactly like the photo, not the slightest flaw or imperfection...but they didn't pass the tooth test. I returned them, informing the seller that I believed they were man-made shell pearls. She just wrote back saying she had them tested by a GIA certified gemologist and that they were NOT shell pearls, but it was not certain whether they were cultured freshwater or saltwater. (?????????)

Frankly, I think she's lying, but rather than get into it, I'm just waiting for my refund. I'd really appreciate some feedback, though. What do you think? Did I just blow it by returning these? Or is she a crook (or to put it more kindly, mistaken...)

Thanks! Sheri
