South sea or larger baroque Akoya?

@Gloriahahaja, you can learn more about pearls in the many articles right here on Pearl-Guide, and also I recommend the PearlsAsOne course (you can take it free with a code), and also I recommend Renee Newman's excellent book, Pearl Buying Guide, 6th edition, available on Amazon.
There is a lot to know about pearls! They are more weird and wonderful than most people know!
