Levinton pendant amber glass chandier

My aunt gave this lamp to me over 20 years ago. I was told it was a tiffany lamp. However, the glass is all separate pieces. I am pretty sure its an antique, and it has the stamp of Levinton on it. My aunt had this lamp when i was a little girl. Must be between 40-50 years old.

I am wondering if anyone has some info they can share with me.

Thanks
