Hi - welcome to the GMB. Sorry not a clue as to the maker or origin of this piece, and though I could be wrong can't imagine for a moment that this is a genuine antique sweetmeat glass. The wider diameter at the top of the bowl is more or less copying the shape of middle C18 sweetmeats, and is a design often referred to as 'pan-topped' - you might try using this word as part of a search description, though whether it will help is anyone's guess - you may just end up with a lot of C18 sweetmeats. I think you're correct as to the mention of this shape having something in common with a candle holder - some mid to late C20 designs for candle holders do have this foot/stem/wide bowl appearance, and often with a much longer stem.
The GMB doesn't per se have a reference archive of modern/current glass designs/shapes, and unless someone recognizes this one, then we're probably no wiser than you - other than which the folk here will offer the suggestion of some commercial sites but which you may have already viewed. The only sales site that comes to mind off hand is the Replacements.com who do sell crystal - don't know if you've tried them yet. I wonder if someone like Dartington ever made this shape - perhaps someone here might know.
Sorry to be negative - of course you could always invest in mid C18 Georgian pan-topped sweetmeat glasses

Others here may possibly have the answer you need - fingers crossed.
