I think with the moulded twist and the white spiral it is Tiger :!:
My dealer has your shape, undulating forms, decanters, and lots of my type of vase - they come in many colours from bright red, orange, amethyst, green - to light olive and beige.
The base of my item is the same as your vase Tiger and the green decanter shown by Anne.
So a connection has been made - Many of the items in my dealers shop have the G Hardy sticker on - note 'Italian Art Glass' - some also have a red and gold foil sticker similar to but not Seguso.
I think the stickers give a date of 1970s - I don't know if G Hardy imported Alrose or indeed who else imported Alrose
This is their sticker Alrose
from a large glass goblet - not like our pieces at all auction link
Note that the label like the G Hardy sticker says 'Italy'
