Pearl necklace

[JulieARod]

We recently found this necklace in a safe while cleaning out my grandmother's house.
I honestly don't know anything about pearls or how to tell of they are real or costume jewelry.
Is there anyone that can point me in the right direction to see if there is any value in this necklace?
I've tried searching online but I can't find anything that's the exact same.

Thank you!
Julie
