Italian Bud Vase - Possibly 1974

I have this Italian bud vase (possibly made in 1974), shaped like a flying saucer. I thought it might have been Bertoncello but I've been told it isn't. Does anybody have an idea? Thank you

I’ve never seen anything quite like it. I love it. It really is like a flying saucer!

There’s a similar patterned vase but different form and no mark for sale on Etsy, and something with similar colours at the Burringbar gallery on Facebook. So clearly a colour pattern used in 60s, 70s Italy but that’s not telling you anything new.

Thanks, I'll have a look this morning.
