What kind of cultured pearls are these?

[PurpleFigLover]

Could you please help me identify these cultured pearls? The seller states they're cultured pearls but I'm not sure if they are freshwater or saltwater pearls. Thanks.

These would be akoya because of roundness, but not top quality, judging by the hazy reflections.
