Still hoping someone with far more experience than me will jump in here and give their much wanted opinion on what they think this pearl is. I was hoping it might be from the Sea of Cortez. I am fairly sure they sometimes can be only 6 mm. I think some of the lower grade Tahitians come in that size too but then it would not have such a great lustre. So I counted out Tahitian. Doesn't look dyed to me but then I am no expert. It is likely to be a really exotic FW pearl ?????
Also not mine although I wish it were.
