Interesting strand...
If I had to bet for my own sake, I... just wouldn't know what they for sure are and consider the 'bargain' status of the piece.
The clap appears to have been restored - at least. Obviously the pearls are not perfect - even the seller doesn't pretend as much. But naturals are excused quite a bit more, as obviously you know.
You know what? I hope someone familiar with the early cultured pearls - the fist Akoya - would come on this thread and say: no, these look nothing like the early cultured baroque.
I hope this post does not offend anyone. I do not intend to disparage
the item: just to have an open discussion about what can be known from a picture, what more experiences pearl fans look for
I do not know all that much, and to me some of the pearls seem to have typical natural shapes and blemishes, other appear as slightly baroque cultured.
