Well, maybe they are not dyed then. That would make me happy. Also, the first baroque akoyas, which are almost the same darker blue color in every pearl, are owned by my mom. She bought them brand new at the military base in Japan, probably in the 70-80s and still has the receipt. I think she paid $520 for them then, and that was when the exchange rate was about 200 yen to the dollar (the dollar has since decreased in strength by half). I don't know why I didn't think to take a photo of the receipt when I took picture of those pearls. It did say natural pearls but I'm pretty sure these were dyed.
