I was so sure this vase was Bohemian, because of the shape of the vase, because it was unsigned, and because the deep intaglio engraving is within a medallion. But then another glass collector said he thought the engraving was Scandanavian, so now I'm not sure at all. There is a large polished pontil (as shown) on a highly polished and edge faceted base, top, and sides. It's 8" tall, quite heavy, and "tings" when struck (not the bell tone of lead crystal, but much closer to the sound than the dull thunk of most glass) if this is useful information. Can any of you tell whether this is indeed, a Scandanavian vase?
