Although your vase looks like it could be a Scandinavian shape, I don't think it is. Although it's pretty, the blue colour doesn't feel right to me. It's a little too 'brassy', and the Scandi blue is generally gentler colour.
The glass on the whole looks a little too thin, and although most Scandi vase pieces are cased, yours isn't.
I would say this vase isn't Scandinavian, based on those three observations. This is only my opinion though. Good luck with Flickr...I hope you find some help there.
