Hi, I hope someone out there may recognise this or know something about this vase as I'm stumped!

The vase is massive (10"h/8"w) and weighs 2.1kg. The body is of clear glass which has a frosted finish on the outside, though is clear and smooth inside. The design is 'applied' to the exterior and is in muted grey/beige/mauve colours - there is an 'art deco' geometric design and an image of an iris. There is a signature / manufacturer name but it is v worn/faded. There is no pontil mark but I guess this may have disappeared if the vase was acid dipped(?).
Pictures included so please take a look and send me your best guess!
Thanks for your time,
V
