Hi - this reminds me of the glass made at the shortlived Sunderland Glass Works which was situated at the Glass museum in Sunderland (Monkwearmouth). They were active about 3 years and went bump about 2000. Shape, colour scheme (and layout) and finish to rim look right. They did a plainer finish like this and also a more iridised Tiffany style look. Colours were supposed to be inspired by stained glass and Hartley Wood etc. Not 100% sure but certainly very similar.
Cheers,
Richard
