That looks just like a vase I found about 10 years ago for $2 at a resale shop LOL.
The one I have appears to be mixed, non-ferrous metal with an acid+applied heat patina.
I noticed yours has a cork(?) on its base. If possible, remove the cork and see if there is a makers mark
like the one pictured below. (I'm still trying to find more info). Awhile back I took mine to an
antique dealer and he offered me $75 for it. . . which I declined. He thought the vase I had might
date early 20th-century. This is about all I know.
Hopefully someone else will chime in that has some additional info.
