I don't understand how they can sell authentic Tahitian Pearls this cheap but I will believe that they are authentic and be happy that I got such a great deal. I bought this pair of earrings, a ring and the full necklace and they certainly will get people stares. My sister bought a necklace with 1 single pearl in Tahiti and it was less than half the price of my necklace, which have more than 30 pearls, so that gets me scratching my head. All I can say is that regardless of how they do it to get such good prices, I am really thankfull because all of my Tahitian Pearl jewelry purchased here at Overstock (and they are all Miadora's) are breathtaking and I totally recommend them! Thank you Overstock, you did it again!
