Real or Fake freshwater pearls

[chitra]

I got two strands of pearls in Amazon -- both freshwater and they claim to be 100% nacre. I see a part of some pearls being very dull in one of the strands and in the other strand I see slight peeling like outlines . Here are some magnified pics . It will be great folks with experience in freshwater pearls can comment if these are normal for natural pearls or these are fake.

They look like low quality bead nucleated freshwater pearls.

The first three pics are a different strand from the last two -- by bead nucleated freshwater pearl you mean the last two pics?

All of the photos look to me like bead nuked FWP.
