Thanks for your comments both i am afraid it is a little odd piece of glass when looking under
a loop it appears to have a rich pink only on the internal surface inside which comes up just to within a few
mm of the top. The glass is quite thick and looks as though it has been treated with a surface colorant or
similar. Both internal and external have an iridescence like petrol on water. I though it might have been an
a piece of Venini or similar but not at all sure really ..sadly got a dink internal knock near base still nice
