I was afraid when I ordered my white Tahitians that they would be too similar to my silver-blue akoyas, but they are not. My silver-blue akoyas look almost round, while the white Tahitians look very different. Some of my white Tahitians are half and half, and some of them have all sorts of free form madness going on around them! And the Tahitians have a much more sharp silver luster than the akoyas (which surprised me). I adored my akoyas before receiving the white Tahitians, but I am very much enamoured with the Tahitians right now.
