I do think it's Isle of Wight Studio Glass, but not Azurene.
Azurene is a coloured glass base with finely broken up silver and gold foil on the surface. This has the glad foil background, but iridescent ribbons of glass over it.
Azurene has been produced since '78, I think this is from a range with a much shorter life span - and it's a bit more sophisticated than Azurene. I'm not up on pws, often designs can look very different on them from other items. However, I suspect this could be Golden Peacock. This was produced between '82 and '04, and is a very highly desirable range.
Or it might be "British Museum", a scarce and desirable beast.. but it's very hard to tell from your pic, I'm afraid. I can't see the whole pattern, I can't make out details.
