ooh that's a weird concept that the foot and the stem are hollow right the way up to the bowl

Were the foot and stem blown as one piece presumably?
Ivo, not totally disagreeing re Bohemian, but something is a bit 'different' about OP's glass from anything I've seen. The shape of the bowl and the flared rim just jars somehow. The foot makes me think 1860's, but the gilding on the clear glass rather than on the white enamel overlay and the style/ type of gilding makes me think earlier maybe 1840-1850 (very similar to that used on hyalith glass during the 1840s).
Harrach did use something similar to that heart shape motif but a tiny bit different in the design. That's on a decanter (will have to look date up later).
The rosaline colour the gilding the shape of the bowl and the flared rim are all a little unusual. I shall try and look through my book this weekend to see if there is any match.
It's lovely btw - it would look very at home in my little overlay collection
