Topic: Dark blue-purple goblet...any ideas to the date

[SteveM]

20 odd years ago we bought a pair of these glass goblets.
The colour is a very deep purple-blue( sort of like UV blacklight fluorescent tubes).
From the superb ring they have when tapped, possibly crystal( or is that not a test for crystal?!).

Pontil mark is not ground down.Height 13cm(5").

Any ideas as to whether they are old?TIA.
