What kind of pearls?

[Scully5473]

Could anyone tell me what kind of pearls I have. I have no idea. Some are close up but they are the same pearls as the 45 separate pearls in the photos. I'm 90% sure they are fresh water but would love some information anything will be greatly appreciate. Ty

Just due to their color and shape I also believe they are Chinese freshwater pearls.
The zoomed photos look interesting due to the surface irregularities, but don't know if they are real or just an optical effect due to the camera.
