Hi wennap, welcome to the Board.
What is it about the vase that makes you think Bohemian? And is it really "cut to amber"? Is there an obvious amber layer beneath the purple? Maybe the "amber" in the cuts is actually gold leaf?
I wonder if this could be a British item.
Also, could you please give the sizes - height and width at widest point. And it could be useful to show a photo of the rim at an angle to see the how the edge of the rim is actually worked. And another photo showing how the base is finished.
