Hello Chriss
Your celery vase is almost certainly wheel engraved rather than etched - which was a wet acid process - and has a baluster shaped stem.
It might be C19, but possibly could be a little later. Wheel engraving was a method of decoration used commonly in the Victorian era. Can you see and small whiteish or black pieces of grit within the glass - this might help to confirm Victorian.
If it does have a yellowish tinge this might indicate a non-lead glass - does it ring when flicked?
As to origin and maker, you'll almost certianly never know - celery vases were one of the most commonly produced designs in glass - made in their millions in every manner of shape and style - pressed and cut - and in most countries, probably. They're seen commonly still at most fairs and markets.
Would suggest that if this has a ground/polished pontil depression (on the underside of the foot) then possibly late Victorian.
