Thanks for requesting me on this. Have you ever removed it from the base and looked in strong window light for an etched glass mark on the bottom or side? I have attached an example of what to look for.
Ok I will ask him to try this and will let u know
This is a circa mid to late 1800's crystal acorn newel post with bronze base, maker unknown.
I added photos of how these pieces were used, and by the size of the one your friend has,
it was in a very large home with an impressive staircase.
My first impression is that this is a European piece, possibly French (Baccarat Glass) in origin.
The value is $600 to $800 retail.
Do click the stars after you have read this answer.
You are correct. I was not aware that it came apart and that would eliminate it as a newel post.
I would have to put my tail between my legs and quietly walk away on this one and say I don't know what it is!
Would you like for me to open this up for another expert to answer?
Sure, it has been great working with you and I hope you will still consider me for other items. I will not be able to respond here once I opt-out, so good luck!
My name is*****'m a certified appraiser, and I'd be happy to help.
Is the bottom bowl solid, or does it have a hole in it?
Is it attached to the bronze base, or just resting on it?
Thanks. Give me some time while I reach out to some colleagues.
Sorry, I"m also at a loss on this one!
