Honestly, I have no idea. However my thoughts if it were mine, would be that it might date mid 19th based on the type of foot and the faceted 'bulbous' stem. The hole in the base of the bowl leads directly into a hollow stem and that makes me wonder if there should have been some form of trumpet or epergne flute placed into it.
Have you checked out makers like Bakewell Pears? ( I think that is what I remember from searching one of mine. However I really have no idea at all about American glass I'm afraid)
And also wondering if it
might
be French ... but that really is just a cursory 'wondering' based on the stem and foot.
One more request? could you take a photo close up ish (but not too close that it's out of focus or unrepresentative) of the textured surface please?
Not sure it will help but I'm very curious to know what it looks like close up.
Thanks
