Was something special until I cracked it badly

Such a shame but never mind - holds lots of memories.
Never found anything to rival it in terms of colours. There were others there - after I cracked it I went back to try and get another one of course. But they were all one colour or two colours. It was the only one of 5 colours

Measures about 32cm tall by 23cm wide including handles so it's a big vase.
Better pics attached.
also have this scent bottle given as a present and have always wondered if it was same maker (pic at bottom).
I've found another different technique but same flat polished base with tiny pontil half moon scar that says Gambaro e Poggi and two others again, different technique but same/similar shape and stopper. So it's possible I guess.
Also found these two in a similar shape but different neck rim application:
