It's real pearls,
And looks to be from around 1920's
1930's Art Deco / art Nuevo style

I'll get back to you in a couple of three days.

Welcome to Tnet.

I am not sure exactly what you have here but I can tell you that it is rare.
These appear to be clam pearls or similar.
This is one heck of a cool piece... and worth something.. just cannot tell what.

Maybe someone here will recognize the makers mark for you.
