Help Identifying irradiated Akoya

[Joseph Wallace]

Hello Looking to get expert opinions on blue gray Akoya. Any tell tale signs irradiation to look for?

 

[Pearl Dreams]

Are they being sold as akoyas? Akoyas are not usually that dark, even the blue gray ones.

Can you post photos of the entire strand?
What is the metal of the clasp?
Size of pearls?

I'm thinking maybe either dyed fwp or Tahitians.

Those look like freshwater, I agree with pearl dreams
