I think the leaves are meant to represent stylised acanthus leaves.
There are some similarities between yours and this one on ebay in terms of the gilded decoration style, the white over green and the 24 point white overlay cut star on the base.
Doesn't help with id of course.
https://www.ebay.co.uk/itm/203117656496There were many many pieces of overlay cut to colour pieces made in the Biedermeier period and later.
I could be totally wrong but I think yours belongs around 1870 ish.
I could also be wrong on this but I don't think it has anything at all to do with the blue over white becher from Meyr's Neffe. That has a totally different look and feel and period feel to me. That becher is special because of the blue used, the cutting and design on it is relevant to it's period of c,1840s etc. It's just so totally different to your piece in my eyes.
