other than telling you that the obvious conclusion would be Finnish or Swedish - I have regrettably drawn a blank in the books that I have, regarding this particular shape, which is what the experts call 'complex'. It is indeed 'modern' in the sense that is second half C20 - assuming that is what you were implying, but I can't see the base detail too well, so unsure of the extent of wear. It has what is termed a 'paperweight' base i.e. a clear base, indicating that technically it is described as 'cased' glass (clear over a colour). The colour seems a little pale for amethyst, but that may mean nothing significant, although most pieces described as such are a little deeper. There is something called 'raspberry pink' also. We now need an expert on Scandi. glass
