hi kyran - the shape of your glass does have some similarity to a sweetmeat or dessert - and possibly not intended as a drinking glass in view of the scalloped rim.
Unfortunately, your pix are too small, and when magnified lose their detail - we need some more please with the first dimension about 700 or just less. Not that this will provide a guaranteed maker and date, but might help someone here to narrow down to a period of manufacture plus, possibly, even a country of origin - a maker you almost certainly won't get. Most glass isn't signed, and very specific characteristics are necessary in order to provide a maker - this probably doesn't have those features being simply a piece of clear, unsigned, cut glass.
Look forward to seeing more pix.
