The Freshadamas were selected to match the pearls in the clasp on my grandmother's old worn out akoyas, so they are very white. The natural white Hanadamas are also very white. And they're both 8 mm pearls. When they are right next to each other, you can tell the difference. The freshies are more satiny looking, and the Hanadamas are super shiny with gorgeous orient, but it's subtle.
Funnily enough, when I where them together, most people think the freshies are real and the Hanadamas are fake, because they look too good.
