I'm a little surprised that the epergne you picture went for as much as £200, even though this sort of frilly Uranium glass is rising in price lately (which is good for me, as a lot of my collection is now worth about twice what I paid!

), as I think it's a 'marriage'. The central flute looks to me to be a different colour glass from the side flutes. Have you tested it under UV light? I wouldn't be surprised if there was a difference in the way they fluoresce. Personally, that's not a great problem to me, as I have an epergne which is a 'marriage' too. It was a way of getting one for less than the cost of a 'prefect' version. I'll attach a picture of mine.
I know there is a glassblower in Bristol who is making reproduction epergnes, which are very beautiful, but I worry that he has depressed the market for epergnes a little, as people don't know if they are getting a genuinely old one, or a modern version. I suppose at least collectors know that if they buy a 'marriage' it's more likely to be old!

Mind you, I know epergnes are of limited appeal, as they take up a lot of space and are not the sort of thing that most people would collect several of!
And the debris in those flutes is going to be very difficult to clean out, I can tell you from experience!

I cleaned mine when I first got it, and now I just let the dust accumulate! :24:
