Pearl identification help please

[La Vita Logue]

Have come across some more pearls that I would like your help identifying please

The first set has been restrung in what feels like fishing line. I have no doubt these tiny pearls are real but want info.

Images 3 & 4 I can’t decide. Pass tooth, weight and cool test but

Confident that images 5 & 6 are cultured .

Thanks in advance for help

I'm not sure if the images are in the correct order from your post. My guess is that 966 and 967 are imitation, but it could be image quality.

Yes they appear to be in order and yes I agree imitation or cultured on those
