An elegant vase. Just to clarify please, is the base polished completely flat? I would expect this with a possible Czech piece, but if the pontil rod mark is polished into a concave central circle on the base, this would make Czech more doubtful.
If totally flat, it is possible to contact Moser and ask them about this piece, they have been very helpful with my enquiries, with cut pieces like this, the answer should be very clear from them, as they have a historian on site who has a lot of knowledge. (However, the Moser option is only one of a few possibilities).
