Please help identify my pearls?

[Green]

Hi everyone,
please could you help identifying this pearl necklace?
It is marked silver on the clasp and a vintage piece.
Just wondering if I could identify it more specifically as salt or freshwater or Akoya!
Thanks in advance for sharing your knowledge and insights!

They look like akoya pearls to me (saltwater).
