Murano or not

I came across these in my travel in Italy. I was told they are Murano and vintage. I am sorry to say I really do not know and thus far my research has not resulted in finding anything close to this style.They are so light it is like holding nothing at all. I love them and can't tell you how I enjoy sharing this beautiful find regardless of what they truly are. I was hoping someone would recognize the period and if they are Murano If anyone know please contact me. Enjoy!
