Antique crystal stem glasses may be French from France?

I purchased a set of vintage crystal glass that I can't seem to find any information on. The lady I bought them from is 65 years of age and these glasses belonged to her grandmother or that's what she was told. She called them VERRE MOUSSELINE and said they came from France. I've found American company's that make similar glasses but nothing with this flower pattern. I've also seen what they call "Rose Point" and Etched glass. Im hoping someone will help me understand the technique and the diffrence from the one I show in the picture.
They are supper thin and delicate.
Thank you all in advance.
