Is this a Louis Rousselet necklace?

Hi everyone,

I have this necklace and the clasp is stamped 'Made in France', and I have seen other necklaces online with the same clasps saying they are by Louis Rousselet. Today in an antique centre I saw necklaces also attributed to him and the brown speckled beads on one looked very similar to these too! So I thought I would share photos of mine to get people's thoughts on it.

I have added the photo of the necklace I took in the case today too.

TYIA for any thoughts you may have on this necklace and its origin!

 

Your beads are knotted, and the stringing looks vintage but may still not be original. The clasp is pretty darned old and it and the beads look like the one in the photo. I'm waiting for actual experts to say one way or another. We get Zip for Rousselet here.
