I think it very highly unlikely to be Isle of Wight.
It's far too thick, it has only gold foil in it, while most Azurene has both silver and gold. Also Azurene is only now being made in purple glass, it certainly wasn't in '93.
I'm only saying very highly unlikely, because glassmakers there do make things on their own (ie. not standard ranges) which are sold from a special shelf kept for these pieces in the shop.
It is concievable that this came from that source - but I still think it very, very unlikely.
