Don't worry, i bet that over 90% is Akoya. If the pearl is really from 1949.

Chase back the history of pearl cultivation, FWP in that period should not have such quality. If you can provide me the size of pearls (can be approx. size, you can take other picture together with the necklaces and a coin to show us the size) and i can tell something much more close.

Probably it is a baroque Akoya from Mikimoto, and I'm quite sure that its worth far much more than US$ 100, given that it is an Antique piece.
